equipment cost	$50,000
required working capital	$30,000
equipment salvage value	$0
Project Annual Cash Inflows	$20,000

2.  Riveros, Inc., is considering the purchase of a machine that would cost $120,000 and last 8 years. After 8 years, the machine would have a salvage value of $29,000. The machine would reduce labor and other costs by $25,000 per year. An additional working capital of $9,000 would be needed immediately. All this working capital would be recovered at the end of the machine's useful life. The company requires a minimum return before taxes of 18% in all investment projects. What is the net present value of the proposed project ?

3. Pro-Mate, Inc. is a producer of sports equipment. The company is considering the purchase of a machine to produce baseball bats. The machine will cost $60,000 and will have a useful life of 10 years. The following annual income and expenses are projected:
