Question 1103992
He deposits $1500, so that is the only part that earns interest.  

For a simple interest rate of 4%, he'll earn  0.04*$1500 = $60 per year.

In 5 years, that will be 5*$60 = $300 earned in interest.   This means he will have  $1500 + $300 = {{{ highlight(matrix(1,2, "$",1800)) }}}  attributable to the original $1500 investment.
