Final answer:
To calculate the CPI for year 2, the total cost of the basket is determined for each year and then compared. The CPI is 116.11, indicating that the correct answer is D. 116.11.
Step-by-step explanation:
The Consumer Price Index (CPI) for year 2 can be calculated using the given prices and quantities of the goods in the basket. To calculate the CPI, we first calculate the total cost of the basket in each year and then compare the year 2 cost to the year 1 cost, which will serve as the base year.
For year 1:
5 toothbrushes at $1.00 each = $5.00
2 tubes of toothpaste at $2.00 each = $4.00
Total cost for year 1 = $5.00 + $4.00 = $9.00
For year 2:
5 toothbrushes at $1.25 each = $6.25
2 tubes of toothpaste at $2.10 each = $4.20
Total cost for year 2 = $6.25 + $4.20 = $10.45
To find the CPI for year 2, we use the following formula:
CPI = (Total cost of the basket in year 2 / Total cost of the basket in year 1) * 100
CPI for year 2 = ($10.45 / $9.00) * 100 = 116.11
Therefore, the correct answer is D. 116.11.
