Final answer:
The accounting profit of the firm is $50,000.
Step-by-step explanation:
The accounting profit of a firm is calculated by subtracting the explicit costs from the total revenues.
In this case, the firm had sales revenue of $1 million, labor cost of $600,000, capital cost of $150,000, and material cost of $200,000.
Therefore, the accounting profit can be calculated as follows:
Accounting profit = Total revenues - Explicit costs = $1,000,000 - ($600,000 + $150,000 + $200,000) = $50,000.
