Question

Elle can buy 2 quarts of milk for 3$ or 1 gallon milk for 3$ which is the better deal

Answer 1

2 quarts is half of a gallon, 4 quarts is one gallon. So the question is pay 3 dollars for half a gallon, or pay 3 dollars for one gallon? Which would you do? they both are the same price, but one is half as much.

Therefor, 1 gallon of milk is a better deal.

Answer 2

1 gallon for $3 is the better deal because you're getting twice as much for the same price
