A heat pump with a coefficient of performance of 3.5 provides energy at an average rate of 70,000 kJ/h to maintain a building at 208C on a day when the outside temperature is 258C. If electricity costs 8.5 cents per kW ? h,

(a) determine the actual operating cost and the minimum theoretical operating cost, each in $/day.

(b) compare the results of part (a) with the cost of electrical-resistance heating.
