[tex]\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\\
r=rate\to r\%\to \frac{r}{100}\\
t=\textit{elapsed time}\\
\end{cases}\\\\
-------------------------------\\\\
\textit{so let's see the amount in the parentheses}\\\\
1.0032\implies 1+\underline{0.0032}\impliedby \frac{r}{100}
\\\\\\
thus\qquad 0.0032=\cfrac{r}{100}\implies 100\cdot 0.0032=r\implies 0.32\%=r[/tex]
