The formula for present value is:
[tex]PresentValueofanannuityis=650\cdot\frac{1-\mleft(1+0.045/4\mright)^{-24}}{0.045/4}=13604.87[/tex]In the formula the 0.045 / 4 represents that the 4.5% compounded quarterly, and the 24 the the number of quarters in 6 years.
The present value must be 13604.87 for quarterly withdrawals of $650 for 6 years.
