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 = <T>subtract(70, 28)=42 cookies in a week.
Paul took out 42/7 = <T>divide(42, 7)=6.0 cookies out of the jar each day.
Over four days, Paul took out 6*4 = <T>multiply(6, 4)=24 cookies from the jar.
