Compact fluorescent bulbs are much more efficient at producing light than are ordinary incandescent bulbs. They initially cost much more, but last far longer and use much less electricity. According to one study of these bulbs, a compact bulb that produces as much light as a 100 W incandescent bulb uses only 23.0 W of power. The compact bulb lasts 10000 hours, on the average, and costs $ 11.00, whereas the incandescent bulb costs only $ 0.76, but lasts just 750 hours. The study assumed that electricity cost $ 0.080 per kilowatt-hour and that the bulbs were on for 4.0 h per day. 1)What is the total cost (including the price of the bulbs) to run incandescent bulbs for 3.0 years? Express your answer in dollars. 2)What is the total cost (including the price of the bulbs) to run compact fluorescent bulbs for 3.0 years? 3)How much do you save over 3.0 years if you use a compact fluorescent bulb instead of an incandescent bulb? 4)What is the resistance of a "100 W" fluorescent bulb? (Remember, it actually uses only 23 W of power and operates across 120 V.)

It seems hard to justify spending $4.00 for a compact fluorescent lightbulb when an ordinary incandescent lightbulb costs 50 ¢. To see if this makes sense, compare a 60 W incandescent bulb lasting 1000 hours to a 15 W compact fluorescent bulb having a lifetime of 10,000 hours. Both bulbs produce the same amount of visible light and are interchangeable. If electricity costs $0.10/kWh,what is the cost - purchase plus energy - to obtain 10,000 hours of light from each...

Compact fluorescent lamps (CFLs) have become required in recent years, but do they make financial sense? Suppose a typical 60-watt incandescent lightbulb costs $.35 and lasts for 1,000 hours. A 15-watt CFL, which provides the same light, costs $2.90 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...
