Afamily is evaluating their energy usage. their current electric hot-water heater raises the water temperature to 140°f, which requires 0.10 kwh/gallon at a cost of $0.10/kwh. each person in the family of five showers once a day for an average of 10 minutes per shower. the shower has a flow rate of 5.0 gallons per minute. calculate the annual cost of the electricity for the family showers assuming that 3.0 gallons per minute of the water used is from the hot-water heater.
