6-38 A manufacturer is considering replacing a production A machine tool. The new machine, costing $37,000, would have a life of 4 years and no salvage value, but would save the firm $5000 per year in direct labor costs and S2000 per year in indirect labor costs. The existing machine tool was purchased 4 years ago at a cost of $40,000. It will last 4 more years and will have no salvage value. It could be sold now for $10,000 cash. Assume that money is worth 8% and that differences in taxes, insurance, and so forth are negli- gible. Use an annual cash flow analysis to determine whether the new machine should be purchased
