Question

While waiting in line to buy one cheeseburger for $1.50 and a medium drink for $1.00, Sally notices that she could get a value meal that contains both the cheeseburger and medium drink and also a medium order of fries for $2.75 . She thinks to herself, "Is it worth the extra 25 cents to get the medium fries?" To an economist, Sally's decision is an example of:________.
a. marginal analysis.
b. basing decisions on total, rather than marginal, value.
c. an unintended consequence.
d. the fallacy of composition.

Answer 1

Answer:

a. marginal analysis.

Explanation:

The cost to add the fried will be the cost added to obtain the fries rather than the cost of a single medium order of fries.

This is the basis of the marginal analysis on which the revenue and marginal cost represent the extra revenue granted for an additional unit and the extra cost for producing an unit. In theory, the firm produce when marginal revenue matches marginal cost.
