Answer:
B) A firm should increase quantity as long as marginal revenue is greater than marginal cost
Explanation:
A firm maximizes its accounting profit when the marginal revenue = marginal costs.
Many times we believe that the price of a product is equal to the marginal revenue, but that is not correct due to distortions produced by taxes or other fees (e.g. credit or debit card fees).
Marginal revenue = selling price - taxes or fees
