Answer 1

The balance after 9 years can be computed below

`\begin{gathered} A=p(1+(r)/(n))^(nt) \\ P=300 \\ \text{rate}=\text{ 8\%=0.08} \\ n=9*12=108 \\ t=9\text{ years} \\ A=300(1+(0.08)/(12))^(108) \\ A=300(1.00666666667)^(108) \\ A=300*2.04953023579 \\ A=614.859070736 \\ A=614.86 \end{gathered}`
