Answer:
If discount rate is 11.7% Project B should be accepted.
If discount rate is 13.5% both projects should be rejected
Explanation:
If the Net present value of Project A is higher than that of project B, we will accept project A and vice versa.
Under 11.7% Discount Rate
Net Present Value-Project A = -82000 + 34000 / 1.117 + 34000 / 1.117² + 34000 / 1.117³ = $85.099
Net Present Value-Project B = -82000 + 115000 / 1.117³ = $516.029
Project B should be accepted as it has a higher NPV.
Under 13.5% Discount Rate
Net present Value-Project A = -82000 + 34000 / 1.135 + 34000 / 1.135² + 34000 / 1.135³ = - $2397.49
Net Present Value-Project B = -82000 + 115000 / 1.135³ = - $3347.91
Both projects should be rejected as both have negative NPVs
