Final answer:
The firm's accounting profit can be calculated by subtracting the explicit costs from the total revenues.
Step-by-step explanation:
The accounting profit can be calculated by subtracting the explicit costs from the total revenues. In this case, the firm's total revenues were $1 million, and the explicit costs were $600,000 for labor, $150,000 for capital, and $200,000 for materials. Therefore, the accounting profit would be $1 million - $600,000 - $150,000 - $200,000 = $50,000.
