Answer:
Wallace deliver 14 gallons of orange juice.
Explanation:
Given:
Wallace delivered 7 containers of orange juice to the Apple Tree Restaurant. Each container had 8 quarts of orange juice.
Now, to find the gallons of orange juice Wallace deliver.
As given that each containers had 8 quarts of juice.
So, we get the total quarts of juice first of the 7 containers by multiplying:
Number of containers × Numbers of quarts.

1 gallon = 4 quarts.
So, by dividing 56 quarts by 4 we get:

Therefore, Wallace deliver 14 gallons of orange juice.
