Question

Year Cumulative Benefit (Present Value) Cumulative Cost (Present Value) Difference (Benefit Cost) 0 1 23 4 5 0 100 200 300 500 650 120 180 210 270 450 560 120 -80 -10 30 50 90 In the table above, "Difference (Benefit - Cost)" is "cumulative benefit (present value)" minus "cumulative cost (present value)". The break-even point is in year Please round off your answer to the second decimal place (example: 3.15).
