A set of four “100-year,” sixty (60) watt light bulbs costs $24.95. If H equals the annual number of hours the bulb is used, each bulb provides 100Hhours of light, and the efficiency of each bulb is 80%. A set of four, sixty (60) watt standard bulbs costs $2.60. Each standard bulb provides H hours of light and the efficiency of each bulb is 95%. If the cost of electricity is $0.0574/kWh, how many hours of operation each year will make the costs of the two types of bulb breakeven? Your personalMARR is 5% per year. Assume repeatability. State other realistic assumptions you must make.
