Answer 1

Your answer would be B

Answer 2

C: $747

Explanation:

To find the amount after compound interest, we use the formula:

`a = {p(1 + (n)/(100) })^(t)`

Where a is the result amount, p is the amount he deposited, n being the interest rate and t being the amount of years. Substitute these variables with the amounts in the question to get

`7200 {(1 + (2.5)/(100) })^(4)`

Input that into a calculator to get $7947.45281...

Next, subtract the original amount of 7200 and you will result with

747.45281 which is 747 corrected to the nearest dollar.
