An investment will pay $58,000 per year forever beginning 8 years from today. If the relevant rate is 10% compounded monthly, the investment is worth $______ today.

i think i need to calculate the pv using

fv = pv ( 1+ r) exp n

fv = 58000

r = 0.10/12

n = 12 * 8 = 96

but this does not give me the expected answer that is 275854.88

i don't know where the forever is used ??

thanks for your help
