3. Consider the following cash flows for two mutually exclusive alternatives (one must be chosen). Notice that the IRR is the same for both. Year 0 100,000 $50,000 $51,000 $60,000 27.19% $100,000 S0 0 $205,760 27.19% 2 IRR (a) If the MARR is 15%, which alternative is better using NPV? (b) What is the IRR on the incremental cash flow, Y -X? (c) If the MARR is 27.5%, which alternative is better using NPV? (d) Which alternative would you recommend? Consider MIRR to help make the final decision
