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?

A company sells an item for P10 each. If the manufacturing cost is P60k per month and the labor is P2 each unit. How many units must be sold to be at breakeven point?

Product X currently sells for $12 per unit. The variable costs is $4 per unit and 10,000 units are sold annually with a profit of $30,000 per year. A new design will increase the variable cost by 21% and fixed cost by 11% but sales will increase to 12777 units per year. At what selling price do the break even occurs for the new design?

Calculate the annual worth of a machine that has an initial cost of $35,000, a life of 10 years, and an annual operating cost of $10,000 for the first 4 years, increasing by 1000 per year hereafter. Use an interest rate of 15% per year.

White Oaks Properties builds strip shopping centers and small malls. The company plans to replace its refrigeration, cooking, HVAC, and other equipment with newer models in the entire center built 9 years ago. The original purchase price of the equipment was $766,000 nine years ago and the operating cost has averaged $240,000 per year. Determine the equivalent annual cost of the installed equipment, if the company can now sell it for $160,000. The company’s MARR is 25% per year.   The equivalent annual cost of the installed equipment is $−

Ecology group wishes to purchase a piece of equipment for recycling of various metals. Machine 1 costs $300000, has a tife of 10 years, an annual cost of $30000, and requires one operator at a cost of $72 per hour. It can process 10 tons per hour. Machine 2 costs $180000, has a life of 6 years, an annual cost of $15000, and requires two operators at a cost of $72 per hour each to process 6 tons per hour. Determine the annual breakeven tonnage of scrap metal at i=10% per year.

A remotely located air sampling station can be powered by solar cells or by running an electric line to the site and using conventional power. Solar cells will cost $7000 to install and will have a useful life of 4 years with no salvage value. Annual costs for inspection, cleaning, etc. are expected to be $1600. A new power line will cost $14000 to install, with power costs expected to be $1300 per year. Since the air sampling project will end in 4 years, the salvage value of the line is considered to be zero. At an interest rate of 8.00% per year, which alternative should be selected on the basis of a future worth analysis? (Include a minus sign if necessary.) The future worth of solar cells is $[ and that of electric line is $ (Click to select) :) should be selected on the basis of a future worth analysis.
