Answer:
The consumer price index for February is 122.85
Step-by-step explanation:
Consumer price index: It shows a change in prices for different years in different products and service.
In this question, we use the formula of Consumer price index which is shown below
= Good and services spend on February month ÷ Good and services spends on January month × 100
= $4,300 ÷ $3,500 × 100
= 1.2285 × 100
=122.85
In the question, it is given that take the January month as the base year so we do the same.
Hence, the consumer price index for February is 122.85
