    \bf \qquad \textit{Amount for Exponential Growth}\\\\ A=I(1 + r)^t\qquad  \begin{cases} A=\textit{accumulated amount}\\ I=\textit{initial amount}\to &40\\ r=rate\to 5\%\to \frac{5}{100}\to &0.05\\ t=\textit{elapsed time}\to &12\\ \end{cases} \\\\\\ A=40(1+0.05)^{12}\implies A=40(1.05)^{12}\implies A\approx 71.8342530
