Step-by-step reasoning process: She either won or lost 60 games because 100 - 40 = 60. We know that 1(60 - Losses) - 2(Losses) = - 30 because she lost $30. Therefore 60 - Losses - 2 Losses = - 30. Therefore - 3 Losses = - 90. Therefore, Losses = 30.

Step-by-step reasoning process: If Coco used his oven 25 hours last month and its energy consumption is 2.4 kW per hour, then we consumed a total of 25 * 2.4 = 60 kW on his oven last month. If the price of electricity is $0.10 per kW, then 60 kW would cost = $0.10 * 60 = $6.
The question and answer:
