Company X has been contracting its overhauling work to Company Y for$40,000 per machine per year. Company X estimates that by building a $500,000 maintenance facility with a life of 15 years and a salvage value of $100,000 at the end of its life, it could handle its own overhauling at a cost of only $30,000 per machine per year. What is the minimum annual number of machines that Company X must operate to make it economically feasible to build its own facility, assuming an interest rate of 10%?

The Ajax Corporation has an overhead crane that has an estimated remaining life of 10 years. The crane can be sold now for $8,000. If the crane is kept in service, it must be overhauled immediately at a cost of $5,000. Operating and maintenance costs will be $3,000 per year after the crane is overhauled. The overhauled crane will have zero MV at the end of the 8-year study period. A new crane will cost $20,000, will last for 8 years, and will have a $4,000 MV at that time. Operating and maintenance costs are $1,000 per year for the new crane. The company uses a before-tax interest rate of 10% per year in evaluating investment alternatives. Should the company replace the old crane?

(Ans. - P218 556.05)-PLEASE USE AN ACTUAL FORMULA NOT AN EXCELarrow_forwardA new machine will cost $200,000. Its maximum useful life is 8 years. The expected market value (MV) of the machine at the end of year 1 is $100,000, and it is expected to decline by $15,000 each year afterwards. The annual operating cost (AOC) is projected to be $75,000 during the first year of operation, and it is expected to rise by 15% every year afterwards. Assuming 11% minimum attractive rate of return, calculate the economic service life of the machine. Your calculations need to include a table with the following columns: Year, MV, AOC, Capital Recovery, Annual Worth (AW) of AOC, and Total AW. Illustrate your analysis with a properly labeled chart, featuring the number of years of service on the horizontal axis, and capital recovery, annual worth of the AOC, and total annual worth on the vertical axis (click to format the vertical axis and check the box “Values in reverse order” so that the axis displays rising cost as movement up).

- Your company is considering purchasing a new CNC machining center. The net benefits in the first year will be $50,000, increasing at a rate of $4,000 per year for the subsequent nine years (so the benefits are $50,000, $54,000, $58,000, etc.). You think the company can get a salvage value of $18,000 at the end of its 10-year useful life. If the MARR is 8%, how much can the company justify spending on the CNC machining center?
