Explain how you can compare the cost of two items that are different sizes ANSWER:

From what I can deduce, using the Unit Price is the best way to compare the cost of two different sizes in items. It would depend on the price of the Item per unit to justify buying the larger item over the smaller item and the opposite is true as well.

SAMPLE RESPONSE: First find the unit price for each. Then compare the unit prices. The item that has the lesser unit cost is the better buy.
