Find the total amount in the compound interest account.

Evgesh-ka [11]

$\bf \qquad \textit{Compounding Continuously Earned Amount}\\\\
A=Pe^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$1740\\
r=rate\to 12\%\to \frac{12}{100}\to &0.12\\
t=years\to &5
\end{cases}
\\\\\\
A=1740\cdot e^{0.12\cdot 5}$

bear in mind that the continuously compounding interest is just that, a daily compounding cycle, taking a year as 365days.
