what is the best definition of marginal revenue?\n the possible income from producing an additional item\n the price of producing one additional unit of a good\n the additional income gained from selling an additional good\n the financial gain from business activity minus expenses
Answer
Brief Explanations:
Marginal revenue is the change in total revenue that results from selling one additional unit of output. It is the additional income gained from selling an extra good. The first option refers to potential income which is not the same as marginal revenue. The second option is about cost (price of producing an additional unit) not revenue. The fourth option describes profit (financial gain minus expenses), not marginal revenue.
Answer:
the additional income gained from selling an additional good
