[15 Points] A lighting system is being designed for an outdoor sports field. There are two choices of lighting fixtures under consideration, each of which will give the same light output. A. Install 30 Metal Halide luminaries, each with a power consumption of 400 Watts. The cost of these fixtures is $450 each. B. Install 40 LED luminaries, each with a power consumption of 150 Watts. The cost of these fixtures is $725 each. Energy is priced at a cost of S0.09/kWh; the cost of money is 5% per year. The fixtures will be used for 2,000 hours per year. Use the Interest Tables attached as the last sheet of this Exam to determine the point in time (years) between which the more expensive fixture will actually be the most cost-effective choice.
