Question #65354

My office is pretty cold. I run a space heater, which has a resistance of 15.0 Ω and
runs off the wall outlet which supplies a voltage of 120 V. If the heater runs for one
hour a day for six weeks, what is the net cost of the electricity that it uses? Assume
that the cost of electricity is $0.13 per kWh.
