Emily needs 5 cups of milk to make a vanilla milkshake. Should she buy a pint, a quart, or a gallon of milk? Explain your answer

A gallon becase if she buys a pint that will equal to 2 cups. and a quart is 4 cups and the gallon 16 cups. the only choice with more than 5 cups is a gallon. the rest are much too small.
