Answer:
3$
Explanation:
For the first vendor, the pickles cost $5 per quart and since there are 4 quarts in a gallon, 5$ x 4 quarts= $20 per gallon.
For the second vendor, the pickles cost 19$ per gallon.
You want to buy 3 gallons of pickles. If you were to buy from the first vendor, then it would be 20$ x 3 gallons= 60$
The second vendor would be 19$ x 3 gallons= 57$
60$ - 57$= 3$ which is what you save in total
