[tex]PV = C* \frac{1- (1+r/n)^{-nt} }{r/n} [/tex]
Where, PV = Present vale, C = Quarterly payments =$52,000, r = Annual interest rate = 8% = 0.08, n = Number of payments per year = 4, t= time of payment in years = 5
Substituting,
[tex]PV = 52000* \frac{1- (1+0.08/4)^{-4*5} }{0.08/4} = $85,027.53[/tex]
The closest answer is $85,027.44
