Next, we will develop the code needed to compute the vector of present value factors. The function to produce this vector has two arguments: A and I. The result should be $(1+)$

$,$ k $=1$ to $119-$A$.$ Let's call this function PV$($A$,$ I$).$ Note that the length of the vector produced by this function should be the same as PROB$($A$,$ G$)$ if the A parameter is the same. You may want to check this.
