Answer:
Both will save the equal amount of money at the age of 75 years
Explanation:
Given:
Amount saved by Cindy per year = $2,000
Amount saved by Bob each year = $4,000
Now,
Cindy started saving at the age of 25 and till the age of 75
thus,
The total number of years for which Cindy saved = 75 - 25 = 50 years
Therefore,
The total amount saved by the Cindy
= Amount saved each year × Total number of years
= $2,000 × 50
= $100,000
and,
Bob started saving at the age of 50 and till the age of 75
thus,
The total number of years for which Bob saved = 75 - 50 = 25 years
Therefore,
The total amount saved by the Bob
= Amount saved each year × Total number of years
= $4,000 × 25
= $100,000
Hence, Both will save the equal amount of money at the age of 75 years
