Betty and Dora started making some cupcakes at the same time. Betty makes 10 cupcakes every hour and Dora makes 8 every hour. If Betty took a two-hour break, what is the difference between the number of cupcakes they made after 5 hours?
Dora made 8 cupcakes per hour for 5 hours for a total of 8*5 = <T>multiply(8, 5)=40 cupcakes
Betty took a 2-hour break so she spent 5-2 = <T>subtract(5, 2)=3 hours making cupcakes
Betty made 10 cupcakes per hour for 3 hours for a total of 10*3 = <T>multiply(10, 3)=30 cupcakes
The difference between the number of cupcakes they made is 40-30 = <T>subtract(40, 30)=10 cupcakes
