Final answer:
The firm's accounting profit can be calculated by subtracting all expenses from the sales revenue.
Step-by-step explanation:
Accounting profit is calculated by subtracting all expenses, including labor, capital, and materials, from the sales revenue. In this case, the firm's accounting profit would be:
Accounting profit = Sales revenue - Labor cost - Capital cost - Materials cost
Substituting the given values:
Accounting profit = $1,000,000 - $600,000 - $150,000 - $200,000 = $50,000
