Answer:

4 gallons

Step-by-step explanation:

Make a proportion

Every 10 servings needs 2 cups of water, and 320 servings needs x cups of water

10/2=320/x

Cross multiply

10*x=320*2

10x=640

Divide both sides by 10

10x/10=640/10

x=64

The recipe needs 64 cups, but we need to find gallons.

There are 16 cups in a gallon. Therefore, we can divide 64 cups by 16 to find out how many gallons it is.

64/16

4

4 gallons of water would be needed for 320 servings
