Answer
${{\$}} 29,709.15$
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 $P=A\displaystyle \cdot\left(1+\frac{r}{n}\right)^{-nt}$
---
$A={{\$}} 80,000,$
$r=0.06,$
$n=1,\ \ t=17$
$P=80,000(1+\displaystyle \frac{0.06}{1})^{-17}\approx{{\$}} 29,709.15$
