Keller Construction is considering two new investments. Project E calls for the purchase of earth moving 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: Use Appendix B. Project E Project H ($25,000 investment) ($27,000 investment) Year Cash flow Year Cash flow 1 $ 6,000 1 $ 18,000 2 9,000 2 9,000 3 10,000 3 7,000 4 13,000 (a) Determine the net present value of the projects based on a zero discount rate. (Omit the “$” sign in your response.) Net present value Project E $ Project H $ (b) Determine the net present value of the projects based on a 9 percent discount rate. (Round “PV Factors” to 3 decimal places and final answer to the nearest dollar amount. Omit the “$” sign in your response.) Net present value Project E $ Project H
