Answer
${{\$}} 654.98$
Work Step by Step
Apply the Present Value Formulas Theorem
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 $P=A\displaystyle \cdot\left(1+\frac{r}{n}\right)^{-nt}$
If the interest is compounded continuously, then $P=Ae^{-rt}$
---
Compounding: continuous,
$A=800, r=0.08,t=2.5$
$P=800e^{-0.08\cdot 2.5} \approx{{\$}} 654.98$
