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 $.49 and lasts for 1,000 hours. a 15-watt led, which provides the same light, costs $3.60 and lasts for 12,000 hours. a kilowatt hour of electricity costs $.125. 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 11 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.)light emitting diode (led) light bulbs have become required in recent years, but do they make financial sense? suppose a typical 60-watt incandescent light bulb costs $.51 and lasts for 1,000 hours. a 15-watt led, which provides the same light, costs $3.70 and lasts for 12,000 hours. a kilowatt-hour is 1,000 watts for 1 hour. suppose you have a residence with a lot of incandescent bulbs that are used on average 500 hours a year. the average bulb will be about halfway through its life, so it will have 500 hours remaining (and you can’t tell which bulbs are older or newer).if you require a return of 10 percent, at what cost per kilowatt-hour does it make sense to replace your incandescent bulbs today? (a negative answer should be indicated by a minus sign. do not round intermediate calculations and round your answer to 6 decimal places, e. g., 32.161616.)
