Economics Grade 12. Use this case. Idutywa grant morning. On grant day in Idutywa a shop sells more maize meal, then orders more from a local mill, and the mill calls in an extra shift. The grant was the first income. The shop's sales and the mill's wages are later rounds of the same spending. If recipients instead spend a large share on clothes that were imported already finished, those rands skip the mill. The local multiplier is larger when the next rand is respent nearby and smaller when the next rand leaves the country. In sentences, say what Circular flow is doing here, from the situation to the result.

In other words — as if you have never seen this before
Circular flow. Households, firms, government and the foreign sector all sit in the flow. When a worker spends at a local shop, that shop's income can pay a baker, who spends again, so an extra rand of income can create more than one rand of total income if it is respent locally. Each round shrinks when the receiver saves, pays tax, or buys imports. An imported good sends the rand out at the first purchase, so the local chain stops, while local food keeps another round alive.

4. Step-by-step working
01 / 07
What it is
In a four-sector flow, one person's spending becomes another person's income, and the multiplier is that repeat, made smaller each time spending leaks into imports, tax or saving.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.

Worked theory
Worked theory. A mine in Rustenburg pays a worker an extra R1 000. She spends R700 of it at a local shop on food, and the shop uses part of that money to pay a baker, who spends at the taxi rank. One person's spending became someone else's income more than once, which is the multiplier in plain words. The other R300 goes on an imported television and leaks out at once. Foreign producers, not the Rustenburg baker, receive that portion. Only the part that stays inside the country keeps being respent locally.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.

Say it back
The multiplier is spending becoming someone else's income again, and imports cut that chain short.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.
05 / 07
Step G — Sense-check the size
Ask: is this the kind of number a Grade 10–12 paper would want? A speed of 3 000 ms for a learner walking, or a probability bigger than 1, means a unit or algebra slip. Estimate first: round the numbers and do the sum in your head.
Why this step: Markers write ‘unrealistic’ in the margin when the method is right but the size is wild. A 10-second head check often finds a missing 10² or a unit that never changed.
06 / 07
Step F — Box the answer with its unit
The multiplier is spending becoming someone else's income again, and imports cut that chain short.
Why this step: A number without a unit is half a mark on a Physics paper, and a marker can miss a Maths answer that is buried in working.
07 / 07
Step H — What the marker is looking for
On an NSC memo you usually earn: (1) a method mark for naming the right formula or idea in words, (2) an accuracy mark for substituting the given numbers with units, (3) an accuracy mark for the boxed answer with its unit. Write those three lines even if you are unsure of the arithmetic — blank pages score zero.
Why this step: First-timers chase the final number and leave the method blank. The memo still pays out for the idea and the substitution even when the last line is wrong.
5. The answer
The multiplier is spending becoming someone else's income again, and imports cut that chain short.

Answer: The multiplier is spending becoming someone else's income again, and imports cut that chain short.
6. Check it like a marker
The answer names the situation, what changed, and the result. It does not stop at a heading.
7. A trap first-timers fall into
A common mix-up is thinking a multiplier means the same person's income doubles, when it means the first spending creates income for other people in later rounds.

Economics Grade 12. Use this case. Bloemfontein till. A supermarket in Bloemfontein takes in less money this month than last month across most aisles. That current sales figure moves with the economy now, so it is coincident. Last year's decision to extend the building, already finished, was based on older plans and does not describe this month. A rise in benefit applications that appears next season would lag this quieter till. Timing, not importance, is what the three labels measure.

In other words — as if you have never seen this before
Business cycles. A leading indicator warns of a turn that has not fully arrived, such as new car sales or building plans falling while factories are still busy. A coincident indicator tracks the present, such as current production or retail sales. A lagging indicator confirms a turn after it has happened. Unemployment is usually lagging, because firms often cut jobs only once output has already fallen, and a lagging indicator used as a warning is late while a leading indicator used as proof of today's output is early.

Worked theory
Worked theory. New car sales and applications for building plans start falling while shopping centres still look busy. Those early falls are leading indicators, and they suggest a downswing is on the way. Months later, factories shorten shifts, and production moving together with the slowdown is coincident. Only after that do retrenchments lengthen the unemployment queue. The queue is lagging. It confirms the downturn and it did not predict it. This is the kind of sequence seen around real downturns such as 2008-09, without quoting a GDP number.

3 · 4 Marks · Public sector
Economics Grade 12. Use this case. VAT loaf and a bonus. VAT takes the same rate on a loaf whether the buyer earns little or a lot, so VAT on its own is not the progressive part of the system. Income tax on a large bonus takes a bigger slice of that extra income than of a small wage. The progressive idea lives in the income-tax brackets. Both VAT and income tax can sit in one budget and still do different jobs. A loaf does not become progressive just because the state collects tax on it. In sentences, say what Public sector is doing here, from the situation to the result.

In other words — as if you have never seen this before
Public sector. Revenue is mostly tax, and spending covers items such as education, grants, health and interest. A progressive income tax means a high salary pays a higher rate on its upper slice than a low salary does, so the higher income contributes more toward services a poor household could not buy alone. When spending exceeds revenue in a year, the gap is a budget deficit and it is financed by borrowing. Public debt is the stock of that borrowing still owed, interest on it uses future tax, and the chain can be understood without any particular deficit figure.

Worked theory
Worked theory. A skilled employee in Sandton pays income tax on a high salary. A no-fee school in a nearby township receives government funding that pays its teachers. The budget link is that tax from higher incomes helps fund spending the household at that school could not cover alone. That is the progressive-tax idea in plain words. If over the years government spends more than it collects, it borrows, and public debt is the amount still owed. Interest on that debt is itself a spending item in a later budget. No official deficit number is required to see the chain from the payslip to the classroom to the debt.

In other words — as if you have never seen this before
Foreign exchange market. Foreigners demand rands when they want South African goods, assets or travel, and they offer foreign currency to get those rands, while South Africans supply rands when they want imports or foreign assets. If demand for rands rises, the rand appreciates, and if demand for rands falls, it depreciates. An importer then pays fewer rands for a foreign-priced good when the rand is stronger, and an exporter who is paid in dollars receives fewer rands for each dollar after that same strengthening. One move helps the importer and hurts the exporter's rand revenue.

Worked theory
Worked theory. Say the rate is R18 to the dollar, and then the rand moves to R16 to the dollar. That move is an appreciation, because one dollar costs fewer rands. An importer in Johannesburg bringing in laptops priced at 500 dollars pays R8 000 instead of R9 000. An apple exporter in the Western Cape who receives the same 500 dollars now converts them to R8 000 instead of R9 000, so the exporter earns fewer rands. The figures are a teaching rate, not a live quote. Appreciation helped the laptop buyer and reduced the apple farmer's rand revenue.

Economics Grade 12. Use this case. Cape Town shirt quota. A quota allows only a fixed number of cheap imported T-shirts into the country in a year. Once that number is filled, extra cheap shirts cannot come in, and local clothing workshops in Cape Town face less price pressure. Shops cannot stock as many bargains as they want, so buyers see fewer of them. A quota restricts quantity. It is not a tax added onto each shirt, which would be a tariff.

Before any working — hunt first
Given
Numbers and units already in the sentence: 12. Copy each one into a column. A name without a number is not given.
Missing
After you copy the given, the letter that still has no number is missing. The paper is pointing at: which would be a tariff. Circle that word — that is the missing variable.
Find
We are required to find: which would be a tariff. Write that as a symbol on the left, with a question mark, before you touch a formula.
Calculate
What we need to calculate: Protectionism and free trade. Then substitute the given, one line at a time, to get which would be a tariff.
In other words — as if you have never seen this before
Protectionism and free trade. A tariff is a tax on an import and raises the shop price, a quota limits how much may be imported, and a subsidy pays local producers so they can cover costs or match a low world price. Free trade lets buyers import without these barriers and pay the world price. Protection can keep a local industry and its jobs, and the cost lands on households as a higher price or on taxpayers if the tool is a subsidy. The gain and the cost do not land on the same people.

Worked theory
Worked theory. South Africa has used tariffs on imported chicken. A tariff on imported frozen chicken raises the price of a pack in a township shop, say from R40 toward R55. A local broiler farmer near Delmas is protected, because the imported pack is no longer much cheaper than the local one, and the farm is more able to keep its workers. The household buying the pack pays the higher price. Free trade would have left the cheaper import on the shelf and put more pressure on the farm. The tariff moves the outcome toward the producer and away from the household, which is the protection trade-off.

In other words — as if you have never seen this before
Economic growth and development. Growth can come from a new mine, a bigger factory or a larger harvest, and it raises what the economy produces. Development asks whether lives change: shorter clinic waits, smaller classes, safer houses, and incomes that reach beyond one gate. Extra output can be real while a nearby school stays overcrowded, which is growth moving faster than development. The gap stays if the new income is not shared, through wages, tax or spending, with the people next to the project.

Worked theory
Worked theory. A new mine outside a town in the Northern Cape increases mineral output and the mine's own revenue. That increase is economic growth. A school a few kilometres away still puts 60 learners in one classroom, with two children sharing a desk. The extra tonnes did not become a second room. Growth happened in the pit, and development in the form of education for those children did not keep up. A fairer share would show as some of that activity funding another teacher or another room. Until then the town has more output and the same crowded class.

Circular flow. Households, firms, government and the foreign sector all sit in the flow. When a worker spends at a local shop, that shop's income can pay a baker, who spends again, so an extra rand of income can create more than one rand of total income if it is respent locally. Each round shrinks when the receiver saves, pays tax, or buys imports. An imported good sends the rand out at the first purchase, so the local chain stops, while local food keeps another round alive.

Worked theory. A mine in Rustenburg pays a worker an extra R1 000. She spends R700 of it at a local shop on food, and the shop uses part of that money to pay a baker, who spends at the taxi rank. One person's spending became someone else's income more than once, which is the multiplier in plain words. The other R300 goes on an imported television and leaks out at once. Foreign producers, not the Rustenburg baker, receive that portion. Only the part that stays inside the country keeps being respent locally.

A coincident indicator tracks the present, such as current production or retail sales. A lagging indicator confirms a turn after it has happened. Unemployment is usually lagging, because firms often cut jobs only once output has already fallen, and a lagging indicator used as a warning is late while a leading indicator used as proof of today's output is early.

Worked theory. New car sales and applications for building plans start falling while shopping centres still look busy. Those early falls are leading indicators, and they suggest a downswing is on the way. Months later, factories shorten shifts, and production moving together with the slowdown is coincident. Only after that do retrenchments lengthen the unemployment queue. The queue is lagging. It confirms the downturn and it did not predict it.

Public sector. Revenue is mostly tax, and spending covers items such as education, grants, health and interest. A progressive income tax means a high salary pays a higher rate on its upper slice than a low salary does, so the higher income contributes more toward services a poor household could not buy alone. When spending exceeds revenue in a year, the gap is a budget deficit and it is financed by borrowing. Public debt is the stock of that borrowing still owed, interest on it uses future tax, and the chain can be understood without any particular deficit figure.

Worked theory. A skilled employee in Sandton pays income tax on a high salary. A no-fee school in a nearby township receives government funding that pays its teachers. The budget link is that tax from higher incomes helps fund spending the household at that school could not cover alone. That is the progressive-tax idea in plain words. If over the years government spends more than it collects, it borrows, and public debt is the amount still owed. Interest on that debt is itself a spending item in a later budget.

Foreign exchange market. Foreigners demand rands when they want South African goods, assets or travel, and they offer foreign currency to get those rands, while South Africans supply rands when they want imports or foreign assets. If demand for rands rises, the rand appreciates, and if demand for rands falls, it depreciates. An importer then pays fewer rands for a foreign-priced good when the rand is stronger, and an exporter who is paid in dollars receives fewer rands for each dollar after that same strengthening.

02 / 07
How it works
Foreigners demand rands when they want South African goods, assets or travel, and they offer foreign currency to get those rands, while South Africans supply rands when they want imports or foreign assets. If demand for rands rises, the rand appreciates, and if demand for rands falls, it depreciates. An importer then pays fewer rands for a foreign-priced good when the rand is stronger, and an exporter who is paid in dollars receives fewer rands for each dollar after that same strengthening. One move helps the importer and hurts the exporter's rand revenue.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.
03 / 07
Worked theory
Worked theory. Say the rate is R18 to the dollar, and then the rand moves to R16 to the dollar. That move is an appreciation, because one dollar costs fewer rands. An importer in Johannesburg bringing in laptops priced at 500 dollars pays R8 000 instead of R9 000. An apple exporter in the Western Cape who receives the same 500 dollars now converts them to R8 000 instead of R9 000, so the exporter earns fewer rands. The figures are a teaching rate, not a live quote. Appreciation helped the laptop buyer and reduced the apple farmer's rand revenue.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.

Why this step: Markers write ‘unrealistic’ in the margin when the method is right but the size is wild. A 10-second head check often finds a missing 10² or a unit that never changed.
06 / 07
Step F — Box the answer with its unit
A stronger rand, fewer rands per dollar, helps importers and pays exporters fewer rands.
Why this step: A number without a unit is half a mark on a Physics paper, and a marker can miss a Maths answer that is buried in working.
07 / 07
Step H — What the marker is looking for
On an NSC memo you usually earn: (1) a method mark for naming the right formula or idea in words, (2) an accuracy mark for substituting the given numbers with units, (3) an accuracy mark for the boxed answer with its unit. Write those three lines even if you are unsure of the arithmetic — blank pages score zero.
Why this step: First-timers chase the final number and leave the method blank. The memo still pays out for the idea and the substitution even when the last line is wrong.

Economics Grade 12. Use this case. Free State maize payment. Government pays a maize farmer in the Free State a subsidy so a bag can be sold closer to the imported price and still cover the farmer's costs.

In other words — as if you have never seen this before
Protectionism and free trade. A tariff is a tax on an import and raises the shop price, a quota limits how much may be imported, and a subsidy pays local producers so they can cover costs or match a low world price. Free trade lets buyers import without these barriers and pay the world price. Protection can keep a local industry and its jobs, and the cost lands on households as a higher price or on taxpayers if the tool is a subsidy. The gain and the cost do not land on the same people.

Worked theory
Worked theory. South Africa has used tariffs on imported chicken. A tariff on imported frozen chicken raises the price of a pack in a township shop, say from R40 toward R55. A local broiler farmer near Delmas is protected, because the imported pack is no longer much cheaper than the local one, and the farm is more able to keep its workers. The household buying the pack pays the higher price. Free trade would have left the cheaper import on the shelf and put more pressure on the farm. The tariff moves the outcome toward the producer and away from the household, which is the protection trade-off.

Economic growth and development. Growth can come from a new mine, a bigger factory or a larger harvest, and it raises what the economy produces. Development asks whether lives change: shorter clinic waits, smaller classes, safer houses, and incomes that reach beyond one gate. Extra output can be real while a nearby school stays overcrowded, which is growth moving faster than development. The gap stays if the new income is not shared, through wages, tax or spending, with the people next to the project.

Worked theory. A new mine outside a town in the Northern Cape increases mineral output and the mine's own revenue. That increase is economic growth. A school a few kilometres away still puts 60 learners in one classroom, with two children sharing a desk. The extra tonnes did not become a second room. Growth happened in the pit, and development in the form of education for those children did not keep up. A fairer share would show as some of that activity funding another teacher or another room.

1. What is the question asking?
Read the question twice. Circle the unknown. Underline every number and unit. The paper is asking: Economics Grade 12. Use this case. Township tour. A tour company in Soweto employs local guides and takes visitors to family-run restaurants. Most of the spending stays in the community, so leakages are small. In sentences, say what Tourism is doing here, from the situation to the result.
In other words — as if you have never seen this before
Tourism. A foreign visitor's spending is an export of services and improves the balance of payments. Each rand spent at a lodge becomes income for guides, cooks and farmers, who spend part of it locally, so the final income is larger than the first injection. Leakages such as imported goods and foreign-owned hotels reduce the effect.

Leakages such as imported goods and foreign-owned hotels reduce the effect.
4. Step-by-step working
01 / 07
What it is
Tourism brings spending into the economy that creates jobs, earns foreign exchange and multiplies through local businesses.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.

Worked theory
Worked theory. Visitors spend R10 million at lodges near Kruger National Park. If locals spend 60c of every extra rand locally, the multiplier is 1(1 − 0,6) = 2,5, so local income rises by R25 million.

Inbound tourism is a service export.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.
05 / 07
Step G — Sense-check the size
Ask: is this the kind of number a Grade 10–12 paper would want? A speed of 3 000 ms for a learner walking, or a probability bigger than 1, means a unit or algebra slip. Estimate first: round the numbers and do the sum in your head.
Why this step: Markers write ‘unrealistic’ in the margin when the method is right but the size is wild. A 10-second head check often finds a missing 10² or a unit that never changed.
06 / 07
Step F — Box the answer with its unit
Inbound tourism is a service export.
Why this step: A number without a unit is half a mark on a Physics paper, and a marker can miss a Maths answer that is buried in working.
07 / 07
Step H — What the marker is looking for
On an NSC memo you usually earn: (1) a method mark for naming the right formula or idea in words, (2) an accuracy mark for substituting the given numbers with units, (3) an accuracy mark for the boxed answer with its unit. Write those three lines even if you are unsure of the arithmetic — blank pages score zero.
Why this step: First-timers chase the final number and leave the method blank. The memo still pays out for the idea and the substitution even when the last line is wrong.

3. Which method — and why this one?
Inbound tourism is a service export.
4. Step-by-step working
01 / 08
Step A — Read the question twice
Slow down. Circle the word that names the unknown. Underline every number and its unit. Do not grab a formula yet — first decide what the paper is actually asking.
Why this step: If you can say the method in a sentence, you will pick the right formula. First-timers skip this and grab the first equation they remember.
02 / 08
Step A2 — Hunt: Given, Missing, Find, Calculate
Given: Numbers and units already in the sentence: no numbers yet — only a name, a diagram, or a worded unknown. Copy each one into a column. A name without a number is not given.
Missing: After you copy the given, the letter that still has no number is missing. The paper is pointing at: What is the answer to keep for Tourism. Circle that word — that is the missing variable.
Find: We are required to find: What is the answer to keep for Tourism. Write that as a symbol on the left, with a question mark, before you touch a formula.
Calculate: What we need to calculate: Inbound tourism is a service export. Then substitute the given, one line at a time, to get What is the answer to keep for Tourism.
Why this step: Do not name the letters yet. First hunt: what already has a number (Given), what has no number (Missing), the word the paper wants (Find), and which formula still contains the missing letter (Calculate).
03 / 08
Step B — Write the given in a column
Copy these onto the left of your page, one per line, with units: every number and its unit in the sentence. Mixing cm with m, or minutes with seconds, loses a method mark.
Why this step: A column with units stops you mixing cm with m, or minutes with seconds. Markers can also see you started correctly.
04 / 08
Step C — Name the method in words
Inbound tourism is a service export.
Why this step: If you can say the method in a sentence, you will pick the right formula. First-timers skip this and grab the first equation they remember.
05 / 08
Working
Inbound tourism is a service export.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.
06 / 08
Step G — Sense-check the size
Ask: is this the kind of number a Grade 10–12 paper would want? A speed of 3 000 ms for a learner walking, or a probability bigger than 1, means a unit or algebra slip. Estimate first: round the numbers and do the sum in your head.
Why this step: Markers write ‘unrealistic’ in the margin when the method is right but the size is wild. A 10-second head check often finds a missing 10² or a unit that never changed.
07 / 08
Step F — Box the answer with its unit
Inbound tourism is a service export.
Why this step: A number without a unit is half a mark on a Physics paper, and a marker can miss a Maths answer that is buried in working.
08 / 08
Step H — What the marker is looking for
On an NSC memo you usually earn: (1) a method mark for naming the right formula or idea in words, (2) an accuracy mark for substituting the given numbers with units, (3) an accuracy mark for the boxed answer with its unit. Write those three lines even if you are unsure of the arithmetic — blank pages score zero.
Why this step: First-timers chase the final number and leave the method blank. The memo still pays out for the idea and the substitution even when the last line is wrong.
5. The answer
Inbound tourism is a service export.
Copy onto your answer sheet — in this order
Answer: Inbound tourism is a service export.
6. Check it like a marker
Does your answer appear as one of the options? Do the units match what was asked (m, N, J, °)? If you put the number back into the original equation, does it still hold? Estimate: is the size sensible?
7. A trap first-timers fall into
First-timers often grab the first formula they remember, mix units (cm with m, minutes with seconds), or drop a minus sign. Write the formula in words first: “this equals that, because…”
