Oregon Ducks, Inc. is considering buying licenses for 12 megahertz of wireless spectrum in the 700 MHz range, which is suitable for delivering television to mobile phones. The 700 MHz signals can travel long distances and more easily penetrate walls and other obstacles. The acquisition cost is $300 million. In addition, because networks that operate in the 700 MHz range are less expensive to build than those in other portions of the spectrum, Ducks estimates annual costs of $24 million over the next 9 years and no salvage value. During the same period, the company expects to generate annual revenue of $40 million by offering television and video to mobile-phone users. Calculate the net present worth of this investment if the company's minimum attractive rate of return (discount rate) is 13% per year.
For a motor to operate a pump, a design engineer must choose the horsepower. Horsepower rating is a design characteristic that can vary from 10 to 40 horsepower. The motor will cost $120 per year to operate, plus $0.60 per horsepower. The running expenses of such motors will be $0.055 per horsepower-hour divided by the horsepower rating. Each year, 9,000 horsepower-hours will be required.   Determine how much horsepower should be supplied to keep the overall yearly cost to a minimal. Demonstrate that your entire cost each year has been reduced.
A diesel engine uses type A filter and high end lubricating oil costing $5.50 per liter. With this filter the oil and filter have to be change every 500 hours of operation, and 5 liters of oil have to be added every 100 hours. This filter costs $148 per piece. 80 liters of oil fill the engine. Another type, Filter B, costing $120 may be used with a lower grade of oil costing $4.80 per liter. However if this filter is used, the oil and the filter had to be change every 300 hrs and 10 liters are added after each 150 hrs the engine is used. Which type of filter would you recommend?
