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=<<5*10=50>>50 minutes
With her sprained wrist it will take her 8*10=<<8*10=80>>80 minutes
80-50=<<80-50=30>>30 more minutes
