Keeping in mind that 6 months is not even a year, since there are 12 months in a year, then is really just 6/12 of a year, or 1/2, thus

\bf ~~~~~~ \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$3500\\
r=rate\to 6.75\%\to \frac{6.75}{100}\to &0.0675\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{monthly, thus twelve}
\end{array}\to &12\\
t=years\to \frac{6}{12}\to &\frac{1}{2}
\end{cases}
\\\\\\
A=3500\left(1+\frac{0.0675}{12}\right)^{12\cdot \frac{1}{2}}\implies A=3500(1.005625)^6
