Claudia brought a 16-cup jug filled with water to the soccer game. She shared the water with her teammates. How can Claudia find out how much water they all drank?

Claudia could estimate the amount of water that her teammates drank by using this process:

1. Measure the amount that Claudia herself drank.

2. Subtract that from the amount of water that the jug was filled with before the soccer game.

3. Find the difference of that and the current amount of water.
