Answer 1

`\bf ~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+(r)/(n)\right)^(nt) \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\to &\$10000\\ r=rate\to 6.25\%\to (6.25)/(100)\to &0.0625\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{quarterly, thus four} \end{array}\to &4\\ t=years\to &10 \end{cases} \\\\\\ A=10000\left(1+(0.0625)/(4)\right)^(4\cdot 10) \\\\\\ A=10000(1.015625)^(40)\implies A\approx 18592.39366677226890`
