How much will it cost to raise the temperature of the water

Your roommate takes a very long shower, until the water in your 40-gallon electric water heater is at an average temperature of 70 F. The water heater has a rating of 12.5 kW.

a) Assuming no additional water flows from the tank, how long will it take for the water temperature to rise to 120 F?

b) If electricity costs $0.07/kWh, how much will it cost to raise the temperature of the water from 70 to 120 F?
