Refer to Figure 15.1. If Dom's maximizes profits, its ________ equals $320.

A) total cost
B) total revenue
C) profit
D) variable cost

When a firm maximizes profits, its total revenue minus total cost equals profit. The question specifies a particular value ($320) but does not directly state what this value represents. However, in the context of profit maximization, it's implied that the firm's operations result in a specific financial outcome. Since the question is about what equals $320 when the firm maximizes profits, and without specific details from Figure 15.1, the most logical interpretation is that $320 refers to an outcome of profit-maximizing behavior, typically related to revenue, cost, or profit itself. Given the options, total revenue is a plausible answer because it's a key figure in calculating profit (profit = total revenue - total cost). However, without the figure or more context, this explanation assumes that $320 is the result of profit-maximizing activities, likely linked to the firm's revenue, as profits and costs are not directly specified in the options.
