Cooper makes 7 apple pies a day. He does this for 12 days. Ashley then eats 50 of his pies. How many apple pies remain with Cooper? Give me reasons, before answering the question
The number of pies Cooper makes in 12 days is 7 pies / day * 12 days = 84 apple pies. After Ashley eats 50 of them, there are 84 pies 50 pies = 34 apple pies. So the final answer is 34.
