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 $.43 and lasts 1,000 hours. A 15-watt LED, which provides the same light, costs $3.30 and lasts for 12,000 hours. A kilowatt-hour of electricity costs $.119. 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 negative answer should be indicated by a minus sign. Do not round Intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) Answer is complete but not entirely correct.

Question
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 $.43
and lasts 1,000 hours. A 15-watt LED, which provides the same light, costs $3.30 and
lasts for 12,000 hours. A kilowatt-hour of electricity costs $.119. 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 negative answer should
be indicated by a minus sign. Do not round Intermediate calculations and round your
answers to 2 decimal places, e.g., 32.16.)
