An initial investment of $480 is invested for 4 years in an account that earns 16% interest, compounded quarterly. What is the amount of money in the account at the end of the period?

At 16% interest compounded quarterly, the value of the account increases by a factor 1.04 every three months. That is becasue 1/4 of 16% is (4%) added to it. Four years is 16 quarters. The value of the account is then
$480.00*(1.04)^16 = $899.03
