Answer 1

$\bf \qquad \textit{Simple Interest Earned}\\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\to& \ 4000\\ r=rate\to 88\%\to \frac{88}{100}\to &0.88\\ t=years\to \frac{15}{12}\to &\frac{5}{4} \end{cases} \\\\\\ I=4000\cdot 0.88\cdot \cfrac{5}{4}$
