Since Mr. P purchased the same dollar amount of vinegar and oil, the number of gallons must be in a ratio of That means that the total number of gallons purchased must be divisble by 3. If the gal barrel was left, then the gallons purchased would be 72, which is divisible by 3. However, the other 5 barrels can not add up to 24 and If the gal barrel was left, then the gallons purchased would be 84, which is divisible by 3.
Since the other 5 barrels add up to 28 and 56, this is the answer. If the gal barrel was left, then the gallons purchased would be 86, which is NOT divisible by 3. Therefore, this cannot be the answer. If the gal barrel was left, then the gallons purchased would be 88, which is NOT divisible by 3. If the gal barrel was left, then the gallons purchased would be 90, which is divisible by 3. However, the other 5 barrels can not add up to 30 and If the 8-gal barrel was left, then the gallons purchased would be 95, which is NOT divisible by 3.
