Assume that a local restaurant sells two items, salads and steaks. The restaurant’s only two customers on a particular day are Mr. Carnivore and Ms. Leafygreens. Mr. Carnivore is willing to pay $20 for a steak and $7 for a salad. Ms. Leafygreens is willing to pay only $8 for a steak, but is willing to pay $12 for a salad. Assume that the restaurant can provide each of these items at zero marginal cost.

How much additional profit can the restaurant earn by switching to the use of a tying strategy to price salads and steaks rather than pricing these goods separately?
a. $20
b. $12
c. $7
d.$6
