Answer
${{\$}} 2955.39$
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 $P=A\displaystyle \cdot\left(1+\frac{r}{n}\right)^{-nt}$
---
$t=$ 6 months = $0.5$ years,
$r=0.03,$
$n=12$ (monthly)
$A=3000$
$P=3,000\displaystyle \left(1+\frac{0.03}{12}\right)^{(-12)(0.5)}\approx{{\$}} 2955.39$
