EP Electric has identified two new methods to treat its cooling water. Alternative I (for inflow) would treat the raw water with a conventional reverse osmosis system so that the cycles of concentration could be increased from 5 to 20. This will result in water cost savings of $360,000 per year and chemical cost savings of $56,000 per year. The initial cost of the equipment will be $2.3 million with an operating cost of $125,000 per year. Alternative B (for blowdown) will treat the cooling tower blowdown water using a highpressure seawater reverse osmosis system to recover most of the water that is sent to an evaporation pond. This option will result in water savings of $270,000 per year. The cost of the system will be $1.2 million with an operating cost of $105,000 per year. Assuming one of the two methods must be installed, determine which is preferred on the basis of the incremental ROR value using MARR of 5% per year, which is a typically low return expected of government projects.…
A process can be completed using either Alternative X or Y, where Y is an automated version of X. Alternative X has fixed costs of $10,000 per year with a variable cost of $50 per unit. If the process is automated, the fixed cost for Y will be $5,000 per year and its variable cost will be only $30 per unit. The minimum number of units that must be produced each year for alternative Y to be favored is closest to:a. Alternative Y will be favored for any level of productionb. 125c. 375d. Alternative X will be favored for any level of production
Two methods can be used for producing solar panels for electric power generation. Method 1 will have an initial cost of $550,000, an AOC of $160,000 per year, and $125,000 salvage value after its 3-year life. Method 2 will cost $830,000 with an AOC of $120,000, and a $240,000 salvage value after its 5-year life. Assume your boss asked you to determine which method is better, but she wants the analysis done over a 3-year planning period. You estimate the salvage value of method 2 will be 35% higher after 3 years than it is after 5 years. If the MARR is 10% per year, which method should the company select

The first cost is $250,000 with an AOC of $76,000. The manager has let it be known that he does not care about the salvage value because he thinks it will make no difference in the decision-making process. His supervisor estimates the salvage might be as high as $100,000 or as low as $10,000 in 3 years, at which time the equipment will be unnecessary. Alternatively, a subcontractor can provide the service for $215,000 per year. The total offshore project MARR is 13% per year.
