Use the same formula as the other post:
For an annual payment P for n years at interest rate r, the value of the investment is
A=Pr^n+Pr^(n-1)+....Pr
=Pr(1+r+rē+...+rn-1)
=Pr(rn-1)/(r-1)
Here A=122000
n=22
r has not been supplied.
Solve for P.
Note: Please do not switch screen names. Doing so will cause loss of continuity.
