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