Light emitting diode (leds) light bulbs have become required in recent years, but do they make financial sense? suppose a typical 60-watt incandescent light bulb costs $.41 and lasts for 1,000 hours. a 15-watt led, which provides the same light, costs $3.20 and lasts for 12,000 hours. a kilowatt hour of electricity costs $.117. a kilowatt-hour is 1,000 watts for 1 hour. however, electricity costs actually vary quite a bit depending on location and user type. an industrial user in west virginia might pay $.04 per kilowatt-hour whereas a residential user in hawaii might pay $.25. you require a return of 9 percent and use a light fixture 500 hours per year. what is the break-even cost per kilowatt-hour? (do not round intermediate calculations and round your answer to 6 decimal places, e. g., 32.161616.)
