Final answer:
The firm's accounting profit is $50,000.
Step-by-step explanation:
The firm's accounting profit can be calculated by subtracting the total expenses from the sales revenue. In this case, the total expenses are $600,000 + $150,000 + $200,000 = $950,000. Therefore, the accounting profit is $1,000,000 - $950,000 = $50,000.
