Consider two investments with the following sequences of cash flows:
n Project A Project B
0 -$120,000 $-100,000
1 $20,000 $15,000
2 $25,000 $15,000
3 $120,000 $110,000
a. Compute the IRR of each investment
b. At MARR=15% determine the acceptability of each project
c. If A and B are mutually exclusive projects, which project would you select based on the rate of return of incremental investment?
