A freezer sustains a cold environment of -24°C and exhausts its heat at 36°C. Assume a Carnot cycle. How much does it cost to remove 288 kJ of heat from the cold environment if the price of energy consumption is 13.5 cents per kWh? Express your answer in cents, to at least two places after the decimal point.
