Problem Analysis

We are given that there are 7 cups of milk in a pitcher and 8 cups of milk in a jar. During lunch, the children drank 5 cups of milk. We need to determine how many cups of milk are left.

Solution 1: Subtraction

We can solve this problem by subtracting the number of cups of milk the children drank from the total number of cups of milk available.

Total cups of milk = cups of milk in the pitcher + cups of milk in the jar Remaining cups of milk = Total cups of milk - cups of milk drank by the children

Let's calculate the remaining cups of milk using this method.

Solution 2: Addition and Subtraction

Another way to solve this problem is by adding the cups of milk in the pitcher and the jar, and then subtracting the cups of milk drank by the children.

Total cups of milk = cups of milk in the pitcher + cups of milk in the jar Remaining cups of milk = Total cups of milk - cups of milk drank by the children

Let's calculate the remaining cups of milk using this method as well.

Calculation

Using Solution 1: Total cups of milk = 7 cups + 8 cups = 15 cups Remaining cups of milk = 15 cups - 5 cups = 10 cups

Using Solution 2: Total cups of milk = 7 cups + 8 cups = 15 cups Remaining cups of milk = 15 cups - 5 cups = 10 cups

Therefore, there are 10 cups of milk left after the children drank 5 cups of milk.
