How much interest is earned on a principal of $575 invested at an interest rate of 7% compounded annually for nine years?

$482.11 in interest

Step-by-step explanation:

Use the compound amount formula.  Calculate the compound amount and then subtract the principle to find the amount of interest earned.

A = P(1 + r)^t, where r is the interest rate as a decimal fraction

This becomes:

A = $575(1 + 0.07)^9, or A = $1057.11.

Subtracting the principal:  A - P:  $1057.11 - $575 = $402.11
