Question 1102238: Twins graduate from college together and start their careers. Twin 1 invests $2500 at the end of each year for 10 years only (until age 31) in an account that earns 6%, compounded annually. Suppose that twin 2 waits until turning 40 to begin investing. How much must twin 2 put aside at the end of each year for the next 25 years in an account that earns 6% compounded annually in order to have the same amount as twin 1 at the end of these 25 years (when they turn 65)? (Round your answer to the nearest cent.)
I have attempted the solution as follows, but it is wrong. Can you please tell me where my work is off?
Twin I
First 10 years (Age 20-30)
PV = 0
Int = 6%
Pmt = $2,500
Solve for FV = $32,951.99
Last 35 years (Age 31-65)
PV = $32,951,99
Pmt = $0
Int = 6%
Solve for FV = $253,271.86
Twin II
PV = $0
Int = 6%
FV = $253,271,86
N= 25 years (age 41-65)
Solve for Pmt = $4,616.31
The $4,616.31 answer is incorrect. My only thought is that I should be starting Twin I at 21 years of age, which would drop the second part of that Twin I answer N value from 35 years (65 yrs - 30 yrs) to 34 years (65 yrs - 31 yrs). I think that would drop the FV for twin I to $239,935.71, and the Pmt for Twin II to 4,355.01. Is that the error here?
Any assistance is appreciated.
