Answer:
1) IRR = 13.61%
2) Since the NPV is positive ($8,464.72), the project should be accepted.
Step-by-step explanation:
initial investment = -$140,000
NCF years 1 to 4 = ($500 x 4 x 12) - $8,000 = $16,000
NCF year 5 = $16,000 + $160,000 = $176,000
using a financial calculator, the IRR = 13.61%
if the discount rate is 12%, then the project's NPV is:
NPV = -$140,000 + $16,000/1.12 + $16,000/1.12² + $16,000/1.12³ + $16,000/1.12⁴ + $176,000/1.12⁵ = $8,464.72
