Answer 1

`\bf \qquad \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+(r)/(n)\right)^(nt) \quad \begin{cases} A=\textit{compounded amount}\\ P=\textit{original amount deposited}\to &\$850\\ r=rate\to 8\%\to (8)/(100)\to &0.08\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, so four times} \end{array}\to &4\\ t=years\to &3 \end{cases}`
