Answer :

The question asks to calculate the amount Marta should earn next year based on the change in the Consumer Price Index (CPI), which provides the rate of inflation. To keep up with inflation, Marta needs to earn approximately $594,921.59 next year.

To determine how much money Marta needs to earn next year to keep up with inflation, we can use the formula:

New Salary = Old Salary × (CPI in the current year / CPI in the previous year)

Plugging in the values given:

New Salary = $543,499 × (110.7 / 101.2) ≈ $594,921.59

Therefore, Marta needs to earn approximately $594,921.59 next year to keep up with inflation.
