The average January temperature in New Orleans is 56 F. The average July temperature is 83 F. Consider a house in the city that exchanges heat with the outside in accordance with the relation dq/dt = A(To - Ti). The subscripts o and I stand for outside and inside.) A has the value 1080 BTU/(hr K). Assume that the inside temperature Ti is to be maintained at 70 F, and that electric power costs ten cents/kWh. Compute the daily average cost for
