Answer :
The current level of the CPI if prices have increased by 220 percent since the base year is 320. The correct answer is d. 320.
Here's the step-by-step explanation:
1. Understand that CPI (Consumer Price Index) is used to measure the changes in prices over time, with the base year as the reference point (CPI in the base year is usually 100).
2. Since prices have increased by 220 percent since the base year, you'll calculate the increase in CPI by multiplying the base year CPI by the percentage increase:
Increase in CPI = Base Year CPI × (Percentage Increase / 100)
= 100 × (220 / 100)
= 100 × 2.20
= 220
3. To find the current level of CPI, you'll add the increase in CPI to the base year CPI:
Current CPI = Base Year CPI + Increase in CPI
= 100 + 220
= 320
So, the correct answer is d. 320.
