question 216

Multiple Choice

Suppose you know the value of the consumer price index (CPI) in year 2 as well as the inflation rate in year 2. Which of the following equations is valid for the CPI in year 1?

• A)
• \[\text { CPI in year } 1 = \frac { 100 \times \text { CPI in year } 2 } { \text { Inflation rate in year } 2 \times 100 }\]
• B)
• \(\text { CPI in year } 1 = \frac { 100 + \text { CPI in year } 2 } { \text { Inflation rate in year } 2 + 100 }\)
• C)
• \[\text { CPI in year } 1 = \frac { 100 \times \text { CPI in year } 2 } { \text { Inflation rate in year } 2 + 100 }\]
• D)
• \[\mathrm { CPI } \text { in year } 1 = \frac { \text { CPI in year } 2 \div 100 } { \text { Inflation rate in year } 2 + 100 }\]
