\(\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\qquad
\begin{cases}
A=\textit{current amount}\\
P=\textit{original amount deposited}\to &\$7000\\
r=rate\to 5\%\to \frac{5}{100}\to &0.05\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{quarterly, means 4 times}
\end{array}\to &4\\
t=years\to &10
\end{cases}\)
how about monthly? well, there are 12 months in a year, so it will the compound cycle is 12, thus \(\bf \qquad \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\qquad
\begin{cases}
A=\textit{current amount}\\
P=\textit{original amount deposited}\to &\$7000\\
r=rate\to 5\%\to \frac{5}{100}\to &0.05\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{monthly, 12 months, thus}
\end{array}\to &12\\
t=years\to &10
\end{cases}\)
