An economy's representative basket of goods consists of only books and coffee. The table below shows the prices and quantities produced for two consecutive years, with 2022 as the base year.
| Year | Price of Books | Quantity of Books | Price of Coffee | Quantity of Coffee |
|---|---|---|---|---|
| 2022 | $10 | 20 | $3 | 100 |
| 2023 | $12 | 22 | $4 | 110 |
To measure the change in the cost of living, what is the total cost of the fixed basket of goods in 2023?

Calculating Market Basket Cost
An economy's representative basket of goods consists of only books and coffee. The table below shows the prices and quantities produced for two consecutive years, with 2022 as the base year.
Year Price of Books Quantity of Books Price of Coffee Quantity of Coffee 2022 $10 20 $3 100 2023 $12 22 $4 110 To measure the change in the cost of living, what is the total cost of the fixed basket of goods in 2023?
An economist wants to measure how much the cost of living has changed due to price inflation alone. They have collected price and quantity data for a representative basket of goods for a base year and a current year. Two approaches are proposed for calculating the basket's cost in the current year:
- Approach 1: Multiply the current year's prices by the current year's quantities.
- Approach 2: Multiply the current year's prices by the base year's quantities.
Which approach should the economist use, and why is it the correct choice for their specific goal?
