Compact fluorescent lamps (cfls) have become more popular in recent years, but do they make financial sense? suppose a typical 60-watt incandescent light bulb costs $0.50 and lasts 1,000 hours. a 15-watt cfl, which provides the same light, costs $3.50 and lasts 12,000 hours. a kilowatt-hour of electricity costs $0.101, which is about the national average. a kilowatt-hour is 1,000 watts for 1 hour. if you require a 10 percent return and use a light fixture 500 hours per year, what is the equivalent annual cost of each light bulb?

Five times the sum of a number and 27 is greater then or equal to six times the of that number and 26. what is the solution set to this proportion?
