A graph plots dollars versus output. A rising line labeled A and a horizontal line labeled C are graphed. Refer to the diagram, which includes the revenue and demand curves for a purely competitive firm. Which of the following statements is most accurate? This firm should produce at the output level where lines A and C intersect. This firm will only earn economic profits if it produces to the right of the intersection of lines A and C. To earn more economic profits, this firm should raise its price. Without information about marginal costs, it is impossible to determine how much output this firm should produce
