Light emitting diodes (LED) light bulbs have become required in recent years, but do they make financial sense? Suppose a typical 60 -watt incandescent light bulb costs $.48 and lasts 1,000 hours. A 15-watt LED, which provides the same light, costs $3.55 and lasts for 12.000 hours. A kilowatt-hour of electricity costs $124. A kilowatt-hour is 1.000 watts for 1 hour. If you require a return of 10 .percent and use a light fixture 500 hours per year, what is the equivalent annual cost of each light bulb? (A negotlve answer should be Indleated by a minus slgn. Do not round Intermedlate caleulations and round your answers to 2 decimal places, e.9., 32.16.)
