The energy utilized is given by the product of power and time. Power is given by the product of voltage and current. Here the microwave draws a voltage of 5 A from a 120 V outlet. The power drawn is voltage * current
=> 5* 120
=> 600 Watt or 0.6 kW
When the oven is run for 6 hr, it uses 0.6 * 6 = 3.6 Kilowatt hour. Each kWh costs $ 0.09 or 9 cents.
Therefore the cost of energy is 0.09* 3.6 = $ 0.324 or 32.4 cents.
it will cost an estimated 6 dollars and 66 cents
