You have a freezer in you apartment that maintains an inside temperature at 12degreeF. The coefficient of performance is 1. 2, and it removes energy from the cold space at a rate of 1200 Btu/hr. If electricity costs $0. 12 per kW hr, find the cost of the electricity in a year (assume 365 days) where the refrigeration cycle is operating 12% of the time.
