Answer: 0.5 gallon
Explanation:
From the question, we are informed that Container a has a maximum capacity of 3 gallons. Container B has a maximum capcity of 14 quarts.
It should be noted that 4 quarts equals 1 gallon. Therefore, 14 quarts = 14/4 = 3.5 gallons
Container A = 3 gallons
Container B = 3.5 gallons
The difference will be:
= 3.5 gallons - 3 gallons
= 0.5 gallon
