A specialty concrete mixer used in construction was purchased for $300,000 7 years ago. It is MACRS-GDS 5-year property. Its annual O&M costs are $105,000. At the end of an 8-year planning horizon, the mixer will have a salvage value of $5,000. If the mixer is replaced, a new mixer will require an initial investment of $375,000, and at the end of the 8-year planning horizon, the new mixer will have a salvage value of $45,000. Its annual O&M cost will be only $40,000 due to newer technology. Use an EUAC measure, a tax rate of 40 percent, and an after-tax MARR of 9 percent to perform an after-tax analysis to see if the concrete mixer should be replaced if the old mixer is sold for its market value of $65,000. a. Use the cash flow approach (insider's viewpoint approach). b. use the opportunity cost approach (outsiders viewpoint approach) Show formulas in Excel screenshots.
