Answer:
The average consumption is higher in University A. than in University B
Explanation:
Marginal cost is known as the cost borne when an extra unit of output is being produced. Sunk cost is the cost once incurred cannot be recovered
The marginal cost at university A is $0 because they dont have to pay anything over and above $500. This $500 is the sunk cost for students at university A. The marginal cost at university B is $2 because they can consume only 250 pounds of food making them careful about the quantity of food they eat.
Sunk cost is not considered while making a decision, so the marginal cost of University A is $0 and that in University B is $2.
Therefore, we are concluding that the average consumption is higher in University A.
