Analyzing a Flawed Cost Calculation
An analyst is trying to measure the impact of price changes on the cost of a representative basket of goods. The basket consists of two items: laptops and smartphones. The table below shows the prices and quantities for a base year and a current year.
| Year | Price of Laptop | Quantity of Laptops | Price of Smartphone | Quantity of Smartphones |
|---|---|---|---|---|
| Base Year | $1000 | 10 | $500 | 20 |
| Current Year | $1100 | 12 | $450 | 25 |
The analyst calculates the cost of the basket in the current year as: ($1100 * 12) + ($450 * 25) = $24,450.
Explain the fundamental error in the analyst's method for the stated goal of measuring only the impact of price changes. Then, state the correct calculation that should have been used.

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?
