Answer

$\$ 9513.28$

Work Step by Step

Consider the Compound Interest Formula: $A=P\cdot(1+\dfrac{r}{n})^{n\cdot t} (1)$ Where $P$ is the principal invested at an annual interest rate $r$, $n$ represents the number of times the interest is compounded annually, and $A$ is the amount after $t$ years. Here we have: $r=5\%=0.05 \\ A=\$ 10000$ and $n=12, t=1 \ year$ Plug the above data into formula (1) to obtain: $P=\dfrac{10000}{(1+\dfrac{0.05}{12})^{(12)(1)}}= \$ 9513.28$
