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?
Paul took out a total of 70-28 = <<70-28=42>>42 cookies in a week.
Paul took out 42/7 = <<42/7=6>>6 cookies out of the jar each day.
Over four days, Paul took out 6*4 = <<6*4=24>>24 cookies from the jar.
