Caleb bought 10 cartons of ice cream and 4 cartons of frozen yoghurt. Each carton of ice cream cost $4 and each carton of frozen yoghurt cost $1. How much more did Caleb spend on ice cream than on frozen yoghurt? Give me reasons, before answering the question
The cost of the ice cream is 10 $4 = $40. The cost of the frozen yoghurt is 4 $1 = $4. Caleb spent $40 $4 = $36 more on ice cream than on frozen yogurt. So the final answer is 36.
