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: Use Appendix B for an approximate answer but calculate your final answer using the formula and financial calculator methods.

Project E					Project H
($21,000 Investment)					($23,000 Investment)
Year	Cash Flow				Year	Cash Flow
1	$	5,000			1	$	17,000
2		8,000			2		7,000
3		9,000			3		6,000
4		12,000

a. Determine the net present value of the projects based on a zero percent discount rate.

b. Determine the net present value of the projects based on a discount rate of 11 percent. (Do not round intermediate calculations and round your answers to 2 decimal places.)
