Final answer:
The profit-maximizing quantity of output is 4 units.
Step-by-step explanation:
The profit-maximizing quantity of output is the quantity at which marginal revenue (MR) equals marginal cost (MC). In this case, the profit-maximizing quantity is 4 units. At this quantity, the marginal revenue is equal to $184, as shown in the table, and the marginal cost is also $184. Any quantity above or below 4 units would result in lower profits.
