Assume the account earns interest rate of 8% compounded monthly

Answer 1

Compound Interest Formula

`FV=P\cdot(1+(r)/(n))^(nt)`

FV = future value of the deposit

P = principal or amount of money deposited

r = annual interest rate (in decimal form)

n = number of times compounded per year

t = time

a) How much will be in the account after ten years?

`\begin{gathered} FV=1500\cdot(1+(0.08)/(12))^(12\cdot10) \\ FV=3329.46 \end{gathered}`

b) How much interest will you earn?

`3329.46-1500=1829.46`

c) How much will much will you deposit into an account now in order to have $6000 in the

account in 8 years. Assume the account earns interest rate of 8% compounded monthly

`\begin{gathered} 6000=D\cdot(1+(0.08)/(12))^(12\cdot8) \\ 6000=D\cdot(1+(0.08)/(12))^(96) \\ 6000=D\cdot1.8925 \\ D=(6000)/(1.8925)=3170.41 \end{gathered}`
