You can purchase a 15-watt compact fluorescent lamp for $1 that is rated to last 10,000 hours. this lamp provides the same light output as a 75-watt incandescent lightbulb that costs $0.50 and lasts 1000 hours. based on an electric energy cost of $0.30/kwh, calculate the money saved over the life of the fluorescent lamp by using it instead of the conventional lightbulb. include the cost of the lightbulbs.
