(b) Keller Construction is considering two new investments. Project E calls for the purchase of earthmoving equipment. Project H represents an investment in a hydraulic lift. Keller wishes to use a net present value profile in comparing the projects. The investment and cash flow patterns are as follows: Project E Project H ($20,000 Investment) ($20,000 Investment) Year Cash Flow Year Cash Flow $ 5,000 $16,000 6,000 5,000 AWN- 7.000 4,000 10,000 i. Determine the net present value of the projects based on a zero discount rate. (3 marks) ii. Determine the net present value of the projects based on a 9 percent discount rate. (4 marks) iii. If the two projects are not mutually exclusive, what would your acceptance or rejection decision be if the cost of capital (discount rate) is 8 percent? (Hint: Calculate the IRR). (5 marks) iv. If the two projects are mutually exclusive, what would be your decision if the cost of capital is (1) 6 percent, (2) 13 percent, and (3) 18 percent?
