Answer:
4. reject both Project A and Project B.
their NPV are negative so are not profitable.
Explanation:
We have to calculate the present value of the projects at their return rate
<u>Project A</u>
Present value of the cash flow - investment = net present value



-75,000 + PV 21,000 + PV 49,000 + PV 12,000
-75,000 + 18,750 + 39062.5 + 8,541.36 = -8646.14
<u>Project B</u>
Present value of the cash flow - investment = net present value
-70,000 + PV 15,000 + PV 18,000 + PV 41,000



-70,000 + 13215.86 + 13972.71 + 28041.18 = -14770.25
