[tex] \bf \qquad \textit{Amount for Exponential Decay}
\\\\
A=P(1 - r)^t\qquad
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &12880\\
r=rate\to 32\%\to \frac{32}{100}\to &0.32\\
t=\textit{elapsed time}\to &20\\
\end{cases}
\\\\\\
A=12880(1-0.32)^{20}\implies A=12880(0.68)^{20}\implies A\approx 5.7556466 [/tex]
