The curves show the marginal revenue (MR), marginal cost (MC), and average total cost (ATC) functions for a firm in a competitive market. Use the area tool to draw the area representing the maximum profit the firm could earn—that is, the profit the firm would earn if it produced the optimal quantity.
Aji Fatou is thinking about opening a hardware store. She estimates that it would cost $500,000 per year to rent the location and buy the stock. In addition, she would have to quit her $85,000 per year job as an engineer. If Aji Fatou thinks she can sell $570,000 worth of merchandise in a year, Aji Fatou's accounting profit is and her economic profit is (please put your answer for accounting profit and economic profit, in numerical values without any dollar sign, comma or decimal place).
