The interior lighting of refrigerators is provided by incandescent lamps whose switches are actuated by the opening of the refrigerator door. Consider a refrigerator whose 50 W lightbulb remains on continuously as a result of a malfunction of the switch. Assume that the refrigerator is opened 35 times a day for an average of 15 s. If the refrigerator has a COP of 1.3 and the cost of electricity is 8.75 pesos per kWh, determine the increase in the energy consumption of the refrigerator and its cost per year if the switch is not fixed.
