Question

Suppose that

​$90000

is invested at

7​%

interest. Find the amount of money in the account after

9

years if the interest is compounded annually. Find the amount of money in the account after

9

years if the interest is compounded continuously.

Answer 1

A=90,000(1.07)^9

= $165,461.33

compounded annually at 7% for 9 years

A = 90,000e^.07(9)

= 90,000e^.63

= $168,984.95

compounded continuously for 9 years
