d. Step 9 of 12^ Calculate incremental investment (B-A): The incremental investment is the difference between the net present value of the Project A and the net present value of the Project B calculated as below: Compute the NPV of incremental investment at 0% discount rate as follows: A B Present value C E F Incremental Present value of Year Cash flows 10023 123456 6 7 8 factor @ 0% investment cash flows Project A Project B Project (B- A) Project (B - A) A B C D E=(D-C) F=(BE) 1.000000 -100 -100 0 0.0000 1.000000 60 0 -60 -60.0000 1.000000 60 0 -60 -60.0000 1.000000 0 140 140 140.0000 Net Present Value = SUM >> 20.000 Thus, the NPV is $20.00 Comment
