Answer:
pay $289,600 for 15 years
Explanation:
we have to compare the present value of both options:
option 1:
pay $2,512,000 immediately, with the same present value
option 2:
pay $289,600 for 15 years
PVIFA, 15 periods, 8% = 8.5595
PV of hte annuity = $289,600 x 8.5595 = $2,478,831
they should choose the second option since the present value is lower.
