Question

Question;Compact fluorescent lamps (CFLs) have become more popular in recent years, but do they make financial sense? Suppose a typical 60-watt incandescent lightbulb costs \$0.50 and lasts for 1,000 hours. A 15-watt CFL, which provides the same light, costs \$3.65 and lasts for 12,000 hours. A kilowatt hour of electricity costs \$0.126, which is about the national average. 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 \$0.04 per kilowatt-hour whereas a residential user in Hawaii might pay \$0.25.You require a return of 9 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 final answer to 6 decimal places. (e.g., 32.161616))
