Final answer:
The firm's accounting profit is $50,000.
Step-by-step explanation:
To calculate the firm's accounting profit, we need to subtract the total explicit costs from the total revenues. In this case, the firm's total revenues are $1 million. The total explicit costs are the sum of labor, capital, and materials, which amounts to $600,000 + $150,000 + $200,000 = $950,000. Therefore, the firm's accounting profit is $1 million - $950,000 = $50,000.
