Answer
${{\$}} 554.09$
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: $n=4$ times per year,
$A=600, t=2, nt=8, r=0.04.$
$P=600\displaystyle \cdot\left(1+\frac{0.04}{4}\right)^{-8}\approx{{\$}} 554.09$
