Final answer:
The firm's accounting profit can be calculated by subtracting the explicit costs from the total revenues.
Step-by-step explanation:
The firm's accounting profit can be calculated by subtracting the explicit costs from the total revenues. In this case, the firm had sales revenue of $1 million and spent $600,000 on labor, $150,000 on capital, and $200,000 on materials. So, the accounting profit would be $1,000,000 - ($600,000 + $150,000 + $200,000) = $50,000.
