Check Your Understanding - Question 2 of 3

How much purchasing power would \[tex]$1,000 according to its 2010 value have gotten you in 2015?

A. \$[/tex]1,006.69
B. \[tex]$1,078.55
C. \$[/tex]1,485.10
D. \$2,112.77



Answer :

Alright, let's determine how much purchasing power [tex]$1,000 in 2010 would have in 2015, accounting for inflation based on the Consumer Price Index (CPI) values. 1. Identify the CPI values for 2010 and 2015: - CPI for 2010: 216.687 - CPI for 2015: 233.707 2. Understand the question setup: We need to calculate how much an amount of $[/tex]1,000 from 2010 would be worth in 2015 dollars. This means we want to adjust the [tex]$1,000 for the inflation between 2010 and 2015. 3. Formula to calculate equivalent value: The formula to calculate the value adjusted for inflation is: \[ \text{Equivalent amount in 2015} = \text{Amount in 2010} \times \left( \frac{\text{CPI in 2015}}{\text{CPI in 2010}} \right) \] 4. Plugging in the values: \[ \text{Equivalent amount in 2015} = 1000 \times \left( \frac{233.707}{216.687} \right) \] 5. Perform the division part first: \[ \frac{233.707}{216.687} \approx 1.078546 \] 6. Multiply this factor with the amount from 2010: \[ 1000 \times 1.078546 \approx 1078.55 \] 7. Conclusion: The purchasing power of $[/tex]1,000 in 2010 would amount to approximately [tex]$1,078.55 in 2015. Therefore, the correct answer among the given choices is: B. $[/tex]1,078.55
