The container that holds the water for the football team is 1/2 full. After pouring in 2 gallons of water, it is 2/3 full. How many gallons can the container hold?

Let x be the capacity of the container in gallons. Half of the container is x/2 and 2/3 of it is 2x / 3. The equation that best represent the given situation above is,

x / 2 + 2 = 2x / 3

The value of x from the equation is 12. Thus, the capacity of the container is 12 gallons.
