Social Studies: Economics: Inflation and the Cost of Living Worksheet

Question 1

In your own words, explain what inflation means. Include one example of inflation that a student might notice in everyday life.

Accepted Answer

Inflation means that the general prices of goods and services rise over time. For example, a student might notice that a school lunch, a movie ticket, or a snack costs more this year than it did last year.

Question 2

A loaf of bread cost $2.50 last year. This year, the same loaf costs $3.00. What is the dollar increase, and what is the percent increase?

Accepted Answer

The dollar increase is $0.50. The percent increase is 20% because $0.50 divided by $2.50 equals 0.20, which is 20%.

Question 3

A simple market basket includes milk, eggs, and a bus pass. In 2020, the prices were $3 for milk, $2 for eggs, and $40 for a bus pass. In 2024, the prices were $4 for milk, $3 for eggs, and $50 for a bus pass. Find the total basket cost for each year and the percent increase from 2020 to 2024.

Accepted Answer

The 2020 basket cost was $45, and the 2024 basket cost was $57. The increase was $12, so the percent increase was about 26.7% because $12 divided by $45 is about 0.267.

Question 4

The Consumer Price Index, or CPI, tracks the cost of a group of common goods and services over time. Why do economists use a market basket instead of tracking only one item, such as apples?

Accepted Answer

Economists use a market basket because one item may not show what is happening to overall prices. A basket with many goods and services gives a better picture of the cost of living.

Question 5

In 2021, $20 could buy 10 notebooks that cost $2 each. In 2024, the notebooks cost $2.50 each. How many notebooks can $20 buy in 2024, and what happened to the purchasing power of $20?

Accepted Answer

In 2024, $20 can buy 8 notebooks because $20 divided by $2.50 equals 8. The purchasing power of $20 decreased because it buys fewer notebooks than before.

Question 6

A worker receives a 4% raise, but inflation is 7% during the same year. Did the worker's purchasing power rise or fall? Explain.

Accepted Answer

The worker's purchasing power fell because prices rose faster than the worker's pay. Even though the worker earns more dollars, those dollars do not buy as much as before.

Question 7

A retired person receives a fixed monthly income of $1,200. If prices rise by 6% and the person's income does not change, how does inflation affect that person's budget?

Accepted Answer

Inflation makes the person's budget harder to manage because the same $1,200 buys less than before. To keep the same purchasing power, the person would need about $1,272 per month.

Question 8

A family's monthly costs changed from last year to this year: groceries rose from $500 to $575, gas rose from $160 to $200, and rent rose from $1,000 to $1,050. What was the total monthly increase in dollars?

Accepted Answer

The total monthly cost rose from $1,660 to $1,825. The family's total monthly increase was $165.

Question 9

Using the same family costs from the previous problem, what is the approximate percent increase in the family's total monthly costs?

Accepted Answer

The approximate percent increase is 9.9% because the $165 increase divided by the original $1,660 total is about 0.099.

Question 10

Decide whether this is most likely demand-pull inflation or cost-push inflation: A popular new video game console is released, and many people want to buy it. Stores raise the price because demand is very high.

Accepted Answer

This is most likely demand-pull inflation because many buyers want the same product, so demand pushes the price higher.

Question 11

Decide whether this is most likely demand-pull inflation or cost-push inflation: A drought damages wheat crops, so flour becomes more expensive. Bakeries raise bread prices because their production costs increased.

Accepted Answer

This is most likely cost-push inflation because the cost of making bread increased, which pushed the final price higher.

Question 12

A city report shows that rent, transportation, food, and health care all became more expensive during the year. Explain why these categories are important when measuring the cost of living.

Accepted Answer

These categories are important because they are major parts of most household budgets. When they become more expensive, families may need more income to maintain the same standard of living.

Question 13

Two cities have different costs of living. In City A, a family spends $2,400 each month on basic needs. In City B, the same basic needs cost $3,000 each month. How much more per month does the family need in City B, and why might wages be higher there?

Accepted Answer

The family needs $600 more per month in City B. Wages might be higher there because workers need more income to afford the higher cost of living.

Question 14

A savings account pays 3% interest in one year, but inflation is 5% during that year. Explain what happens to the real value of the money in the account.

Accepted Answer

The real value of the money falls because inflation is higher than the interest rate. Even though the account has more dollars, the money has less purchasing power than before.

Question 15

Study this situation: The price index was 100 in 2020, 108 in 2021, 117 in 2022, and 120 in 2023. Which year had the largest increase in the price index from the previous year, and what does that mean?

Accepted Answer

The largest increase happened in 2022 because the index rose from 108 to 117, an increase of 9 points. This means prices increased more from 2021 to 2022 than in the other one-year periods shown.
