Answer 1

Given:

Jim opens a savings account with $22,500. His account pays 3.5% interest compounded yearly.

Required:

How much interest does he earn? What is the total value of his account when he closes it?

Step-by-step explanation:

We know the formula for the compound interest

`A=P(1+(r)/(n))^(nt)`

Now, we have P = $22,500, r = 0.035 and time = 5.5 years

`\begin{gathered} A=P(1+(r)/(n))^(nt) \\ A=22500(1+0.035)^(5.5) \\ A=22500(1.035)^(5.5) \\ A=27186.57 \end{gathered}`

Answer:

Interest he earns = 27186.57 - 22500

= 4686.57

Total value of his account = 27186.57
