A division of Raytheon owns a 5-year-old turret lathe used to manufacture fabricated metal products that was purchased for \($96,000\) and now has a financial reporting (non-tax) book value of \($24,000.\) It has been depreciated for tax purposes as MACRS-GDS 7-year property. It has a current market value of \($18,000.\) The expected decline in market value is \($3,000\) per year from this point forward to a minimum of \($3,000.\) O&M costs are \($8,000\) per year. Additional capability is needed. If the old lathe is kept, that new capability will be contracted out for \($13,000,\) assumed payable at the end of each year. A new turret lathe has the increased capability to fulfill all needs, replacing the existing turret lathe and requiring no outside contracting. It can be purchased for \($65,000\) and will have an expected life of 8 years. Its market value is expected to be \($65,000(0.7t) at\) the end of year t. AnnualO&M costs are expected to equal \($10,000.\) If the after-tax MARR is 9 percent, the tax rate is 40 percent, and the planning horizon is 8 years, determine whether to keep and use a contractor or to sell and buy new.

a. Clearly show the cash flow profile for each alternative using the cash flow approach (insider’s viewpoint approach). 

b. Using an EUAC comparison and a cash flow approach (insider’s viewpoint approach), decide which is the more favorable alternative.
