Normally Ann can frost a cake in 5 minutes. However, today she has a sprained wrist and it takes her 8 minutes to frost a cake. How much longer would it take her to frost 10 cakes with her sprained wrist?
Normally, it would take her 5*10=<T>multiply(5, 10)=50 minutes
With her sprained wrist it will take her 8*10=<T>multiply(8, 10)=80 minutes
80-50=<T>subtract(80, 50)=30 more minutes
