An $80,000 baling machine for recycled paper was purchased by the XYZ company two years ago. The current MV of the machine is $50,000, and it can be kept in service for seven more years. MARR is 12% per year and the projected net annual receipts (revenues less expenses) and end-of-year market values for the machine are shown below. When is the best time for the company to abandon this project?

Net annual receipts $20,000 $20,000 $18,000 $15,000 $12,000 $6,000 $3,000

$250,000 is invested in equipment having a salvage value equal to $250,000(0.80n) after n years of use. O&M costs equal $60,000 the first year and increase $8,000 per year. Based on a MARR of 10%, what are the optimum replacement interval and minimum EUAC?
: A machine was purchased and installed 6 years ago for $50000 with a useful life of 10 years. The salvage value is now $5500 and decreasing at a rate of $500 per year. The machine has a maintenance cost of $2000 per year. Assuming a 12.4% MARR, should the company replace the machine this year with a potential new machine that has a EUAC of $3000 per year?

- Peachtree Construction Company, a highway contractor, is considering the purchase of a new trench excavator that costs 300000 and can dig a 3-foot-wide trench at the rate of 16 feet per hour. The contractor gets paid according to the usage of the equipment, 100 per hour. The expected average annual usage is 500 hours, and maintenance and operating costs will be 10 per hour. The contractor will depreciate the equipment by using a five-year MACRS, units-of-production method. At the end of five years, the excavator will be sold for 100000. Assuming the contractor’s marginal tax rate is 25% per year, determine the annual after-tax cash flow.

- Kappa Holdings is looking at a new system with an installed cost of $740,000. This cost will be depreciated straight-line to zero over the project's 7-year life, at the end of which the system can be salvaged for $102,000. The system will save the firm $217,000 per year in pretax operating costs, and the system requires an initial investment in net working capital of $69,000, which will be returned at the end of the project.

- The replacement of a planning machine is being considered by the Reardorn Furniture Company. (There is an indefinite future need for this type of machine.) The best challenger will cost $30,000 for installation and will have an estimated economic life of 11 years and a $2,000 MV at that time. It is estimated that annual expenses will average $15,500 per year. The defender has a present BV of $6,000 and a present MV of $3500. Data for the defender for the next three years are given below.
