Basic Math
Light-emitting diode (LED) light bulbs have become required inrecent years, but do they make financial sense? Suppose a typical60-watt incadescent light bulb costs $.45 and lasts for 1,000hours. A 7-watt LED, which provides the same light, costs $2.25 andlasts for 40,000 hours. A kilowatt-hour of electricity costs $.121,which is about the national average. A kilowatt-hour is 1,000 wattsfor 1 hour. Suppose you have a residence with a lot of incandescentbulbs that are used on average 500 hours a year. The average bulbwill be about halfway through its life, so it will have 500 hoursremaining (and you can’t tell which bulbs are older or newer).
If you require a 10 percent return, at whatcost per kilowatt-hour does it make sense to replace yourincandescent bulbs today? (A negative answer should beindicated by a minus sign. Do not round intermediate calculationsand round your answer to 6 decimal places, e.g.,32.161616.)
