An oven is plugged into a 120 V electrical outlet and "cooks" the food by using a 144 ohm resistor light bulb that converts electrical energy to both light and heat energy. If the light bulb converts 75% of the electrical energy to thermal energy, and the oven is used for a total of 11.6 hours during one month, to the nearest hundredth of a megajoule, how much thermal energy was produced?
