Final answer:
The firm's accounting profit is $50,000.
Step-by-step explanation:
Accounting profit is calculated by subtracting explicit costs from revenue. In this case, the firm's revenue is $1 million and its explicit costs are the sum of labor, capital, and material expenses, which is $600,000 + $150,000 + $200,000 = $950,000.
So, the accounting profit is $1,000,000 - $950,000 = $50,000.
