A 2.4-m-high 200-m2 house is maintained at 22°C by an air-conditioning system whose COP is 3.2. It is estimated that the kitchen, bath, and other ventilating fans of the house discharge a houseful of conditioned air once every hour. If the average outdoor temperature is 32°C, the density of air is 1.20 kg/m3 , and the unit cost of electricity is $0.10/kWh, the amount of money “vented out” by the fans in 10 hours is (a) $0.50 (b) $1.6 (c) $5.0 (d) $11.0 (e) $16.0
