A project your firm is considering for implementation has these estimated costs and revenues: an investment cost of $56417, a maintenance costs that start at $5,000 at end of year (FOY) one and increase by $1,000 for esch of the next four years, and then remain constant for the following five years; savings of $24851 per year (EOY 1-10); and finally a resale value of $31935 at EOY 10 If the project has a 10 year life and the firm's MARR is 10% per yeat, what is the present worth of the project?.
Since many U.S. Navy aircraft are at or near their usual retirement age of 30 years, military officials want a precise system to assess when aircraft should be taken out of service. A computational method developed at Carnegie Mellon maps in 3-D the microstructure of aircraft materials in their present state so that engineers can test them under different conditions of moisture, salt, dirt, etc. Military officials can then determine if an aircraft is fine, is in need of overhaul, or should be retired. If the 3-D system allows the Navy to use one airplane 2 years longer than it normally would have been used, thereby delaying the purchase of a $20 million aircraft for 2 years, what is the present worth of the assessment system at an interest rate of 8% per year?

An oil refinery finds that it is necessary to treat the waste liquids from a new process before discharging them into a stream. The treatment will cost $40,000 the first year, but
process improvements will allow the costs to decline by $4,000 each year. As an alternative, an outside company will process the wastes for the fixed price of $20,000/year
throughout the 8 year period, payable at the beginning of each year. Either way, there is no need to treat the wastes after 8 years. Use the annual worth method to determine
how the wastes should be processed. The company's MARR is 13%.

- Required information In order to provide drinking water as part of its 50- year plan, a west coast city is considering constructing a pipeline for importing water from a nearby community that has a plentiful supply of brackish ground water.
