Question

The formula I = PRT where I = Interest, P = Principal, R = Rate, and T = rime use to calculate the amount of simple interest earned. Solve this formula for T.

Answer 1

$\bf ~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\\ r=rate\to r\%\to \frac{r}{100}\\ t=years \end{cases} \\\\\\ I=Prt\implies \cfrac{I}{Pr}=t$
