Project A has an initial investment of $11,000, and generates positive cash flows of $4,000 each year for the next six years. Project B has an initial investment of $17,000, and generates positive cash flows of $4,500 each year for the next six years Assume the discount rate is 13%. NPV Project A Project B Project selected if A and B are mutually exclusive Project(s) selected if A and B are indpendent: Using the NPV criteria answer these questions. IRR Project A Project B Enter the IRR function. Using IRR for your decision, which project would you select if A and B are mutually exclusive: Using the IRR criteria. Would your answer change if the two projects are independent instead of mutually exclusive? Project C was added to the potential capital budgeting list at the last minute as a mutually exclusive alternative to Project B. O has an initial investment of $17,000, and generates positive cash flow of $37,500 in year six; note years 1 through 5 have NO CASH FLOWS. Assume the discount rate is 13%. NPV Project B Project C $0.00 Enter the NPV function. Be sure to properly account for the initial cost! The value in the yellow cell will fill automatically from the results above Project selected if B and C are mutualy exclusive: Using the NPV criteria answer these questions IRR Project B Project C 0% <.e enter the irr function. yellow cell will fil automatically. project selected if b and care mutually exclusive:using criteria. using because projects c are exclusive would you recommend that or be added to capital budget for this year explain your answer here>
