Give the step-by-step reasoning process and then the final answer. 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?
User
Normally, it would take her 5 * 10 = 50 minutes. With her sprained wrist it will take her 8 * 10 = 80 minutes. 80 - 50 = 30 more minutes.
The final answer: 30.
