Onbec Company is considering purchasing a machine that would save the company $13,500 in cash per year for six years, at the end of which the machine would be retired with no residual value. The firm wishes to earn a minimum return of 8 percent, compounded annually, on any such investment. Assume that the cash savings occur at year-end, and ignore income taxes. Use Table 8C1, Table 8BC2 (Round time value factor to 4 decimal places. Round intermediate and final answers to the nearest whole dollar.) Required: 1. What is the maximum amount that the firm should be willing to pay for this machine? 2. What is the maximum amount that the firm should be willing to pay for this machine, if the machine is expected to have a residual value of $4,000 at the end of six years? 3. The company could buy a machine that had no residual value and offered no cost savings for the first five years, but this machine would offer cost savings of $113,561 at the end of the sixth year. What is the maximum amount that Onbec should pay for the machine
