when electrical appliances whose power usage is x watts is run Y seconds , it uses XXY joules of energy. The energy unit used by electrical utilities in their monthly bills is the kilowatt hour ( Kwh, that is, 1 kilometer used for 1 hour) How much does it cost $0.09 per kilowatt-hour, how much does it cost per megajoules?
