Answer
${{\$}} 6439.28$
Work Step by Step
The present value $P$ of $A$ dollars to be received after $t$ years,
assuming a per annum interest rate $r$ compounded $n$ times per year, is $P=A\displaystyle \cdot\left(1+\frac{r}{n}\right)^{-nt}$
---
$A={{\$}} 10,000,$
$r=0.045,$
$\mathrm{n}=1, \mathrm{t}=10$
$P=10,000(1+\displaystyle \frac{0.045}{1})^{-10}\approx{{\$}} 6439.28$
