Inflation and CPI Practice- Macro 2.8

The video tutorial on ACDC Econ explains inflation and the Consumer Price Index (CPI). It covers how inflation is measured through the inflation rate and index numbers, using the CPI as a key example. The tutorial provides detailed steps on calculating CPI and inflation rates, emphasizing the importance of understanding base years and percent changes. Viewers are encouraged to practice these calculations to solidify their understanding.

What does the inflation rate indicate?

• The base year value of CPI

• The total number of goods in a market basket

• The percentage change in prices over a period

• The absolute price of goods in a year

If the CPI in 1990 is 130, what does it signify?

• Prices have decreased by 30% since the base year

• Prices are the same as the base year

• Prices have doubled since the base year

• Prices have increased by 30% since the base year

How is the CPI calculated?

• By multiplying the current year's market basket value by the base year's value

• By adding the current year's market basket value to the base year's value

• By subtracting the base year's market basket value from the current year's value

• By dividing the current year's market basket value by the base year's value and multiplying by 100

What is the CPI for a year if the market basket value is $60 and the base year value is $50?

• 90

• 110

• 120

• 100

If the market basket value in 2004 is $100 and the base year value is $50, what is the CPI?

• 100

• 50

• 200

• 150

In 2010, if the market basket value is $80, what is the CPI?

• 120

• 80

• 100

• 150

What is the inflation rate if the CPI in year one is 100 and in year two is 125?

• 15%

• 30%

• 20%

• 25%

If the CPI in year one is 125 and in year two is 150, what is the inflation rate?

• 10%

• 15%

• 25%

• 20%

How do you calculate the inflation rate between two years?

• Subtract the CPI of the first year from the second year, divide by the first year, and multiply by 100

• Add the CPI of both years and divide by 2

• Divide the CPI of the second year by the first year and multiply by 100

• Subtract the CPI of the first year from the second year

If the CPI in year one is 80 and in year two is 100, what is the inflation rate?

• 20%

• 30%

• 15%

• 25%
