Compact fluorescent light bulbs cost $6 each and have an expected lifetime of 8000 h. These bulbs consume 20 W of power, but produce the illumination equivalent to 75-W incandescent bulbs. Incandescent bulbs cost about $1.50 each and have an expected lifetime of 1200 h. If the average household has, on the average, six 75- W incandescent light bulbs on constantly, and if energy costs 11.5 cents per kilowatt-hour, how much money would a consumer save each year by installing the energy-efficient fluorescent light bulbs?
