Textbook Question
Chapter 6, Problem 4P
Three mutually exclusive design alternatives are being considered. The estimated sales and cost data for each alternative are given on p. 305. The MARR is 20% per year. Annual revenues are based on the number of units sold and the selling price. Annual expenses are based on fixed and variable costs. Determine which selection is preferable based on AW. State your assumptions. (6.4)

A replacement electric motor is being considered for purchase. It is capable of
providing 200.00 hp. The pertinent data are as follows:
Cost
$5,782.91
Maintenance cost per year

Salvage value
$2.268.56
The motor is used for 400 hours/year and the cost of electricity is $0.06/kW"h (1 hp
- 0.746 kW). What is most nearly the effective annual cost using an interest rate of
10%?
Decision D6, which has three possible choices (X, Y, or Z), must be made in year 3 of a 6-year study period in order to maximize EPW).
Using an MARR of 16% per year, the investment required in year 3, and the estimated cash flows for years 4 through 6,

- Dupont is considering licensing a low liquid discharge (LLD) water treatment system from a small company that developed the process and owns the license. Dupont can purchase a 1-year option for $100,000 that will provide time to pilot test the LLD process or Dupont can acquire the license now at a cost of $1.8 million plus 25% of sales paid annually to the license owner. If they wait 1 year, the cost will increase to $1.9 million plus 30% of sales paid annually. If sales are estimated to be $1,000,000 per year over the 5-year license period, should Dupont purchase the license now or purchase the option now and possibly license it after the 1-year test period?

Model 1 has a life of four years with a first cost of $13,500 and maintenance costs of $1,250 per year in years 2, 3, and 4 (no maintenance costs in year 1). The salvage value for this model at the end of its life is $4,271 (For year 2 the salvage value is $7,594). Model 2 has a life of three years with a first cost of $15,000 and maintenance costs of $700 per year. Its salvage value at the end of its life is $9,300 (year 3).
