A supplier is packing cartons of canned juice. Each carton has 20 cans of juice. Out of the 50 cartons that have been packed, only 40 cartons have been loaded on a truck. How many cans of juice are left to be loaded on the truck? Give me reasons, before answering the question
There are 50 - 40 = 10 cartons of canned juice that are left to be loaded on the truck. This is equal to 10 x 20 = 200 cans of juice. So the final answer is 200.
