A power company charges $0.095 per KW•hr. There is a microwave rated at 1200 W, a TV rated at 60W, and a light bulb rated at 12W. If the microwave is used 5 min a day, the TV 4.5 hours a day, and the light bulb 6 hours a day, how much money is owed to the power company at the end of 30 days for the devices?
