Answer

${{\$}} 626.61$

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: $n=12$ times per year, $A=800, t=3.5, nt=42, r=0.07.$ $P=800\displaystyle \cdot\left(1+\frac{0.07}{12}\right)^{-42}\approx{{\$}} 626.61$
