Compute the amount Alan would withdraw assuming the investment earns interest compounded semiannually.

Compute the amount Alan would withdraw assuming the investment earns interest compounded semiannually.

Explanation / Answer

1.We use the formula:
A=P(1+r/100)^n
where
A=future value
P=present value
r=rate of interest
n=time period.

Hence

A=$37500(1.1)^10

=$37500*2.59374246

=$97265.34

2.We use the formula:
A=P(1+r/200)^2n
where
A=future value
P=present value
r=rate of interest
n=time period.

Hence

A=$37500(1+10/200)^(2*10)

=$37500*2.653297705

=$99498.66(Approx).
