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

• A)
• \[\text { CPI in year } 2 = \frac { 100 \times \text { CPI in year } 1 } { \text { Inflation rate in year } 1 \times 100 }\]

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