There are 70 cookies in a jar. If there are only 28 cookies left after a week, and Paul took out the same amount each day, how many cookies did he take out in four days? Give me reasons, before answering the question
Paul took out a total of 70 - 28 = 42 cookies in a week. Paul took out 42 / 7 = 6 cookies out of the jar each day. Over four days, Paul took out 6 * 4 = 24 cookies from the jar. So the final answer is 24.
