Sarah

Milkshakes

Explanation:

A person has comparative advantage in production if it produces at a lower opportunity cost when compared with other people.

A person has an absolute advantage in the production of a good or service If she produces more quantity of a product when compared with other people.

Sarah produces more hamburgers and milkshakes when compared to Abe. Therefore she has absolute advantage in the production of both milkshakes and hamburgers.

The opportunity cost of Sarah in producing hamburgers and milkshakes are both 10/10 = 1

The opportunity cost of Abe producing hamburgers is 4 / 5 = 0.8 and for milkshakes it is 5/4 = 1.25.

Therefore, Sarah has a comparative advantage in the production of milkshakes because she has a lower opportunity cost (1) when compared with Abe (1.25)
