Answer 1

Answer:

20 cents

Explanation:

The marginal cost refers to the cost of an extra unit. In this case, if she decides to purchase two tacos and a medium drink, she would spend $2.30. The difference between this option and the value meal, that contains three tacos and a medium drink, is 20 cents. The marginal cost of purchasing the third taco if she takes the second option would be 20 cents. If she decides to buy the tacos and the drink for apart, the marginal cost or extra unit cost would be 75 cents.
