[tex]\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$1500\\
r=rate\to 4\%\to \frac{4}{100}\to &0.04\\
t=years\to &5
\end{cases}
\\\\\\
A=1500(1+0.04\cdot 5)\implies A=1800[/tex]
now, he had 3200, he took 1500 for deposit, so, 3200 - 1500, he had left in his pocket 1700.
so after 5 years, he'll have 1700 + 1800.
