frosja888 [35]

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &40\\
r=rate\to 2.5\%\to \frac{2.5}{100}\to &0.025\\
t=\textit{elapsed time}\\
\end{cases}
\\\\\\
A=40(1+0.025)^t\implies A=40(1.025)^t$
