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