Answer:
annuity factor for 20% and 6 periods = 3.326
Explanation:
the IRR represents the discount rate at which a project's NPV = 0
NPV = initial outlay + PV of future cash flows
NPV = 0
initial outlay = -$831,500
PV of future cash flows = $831,500 = cash flow x annuity factor
annuity factor = $831,500 / $250,000 = 3.326
using an annuity table and looking for the annuity factors for 6 periods, we find that the annuity factor for 20% and 6 periods = 3.326.
So our IRR = 20%
