Step-by-step explanation:
A Firm's Accounting Profit Calculation
Based on the provided details, we can calculate a firm's accounting profit by subtracting the sum of all explicit costs from the total revenues. Specifically, the firm had sales revenue of $1 million last year. The explicit costs included $600,000 on labor, $150,000 on capital, and $200,000 on materials. Therefore, to find the accounting profit, we perform the following calculation:
Total Revenues - (Labor Costs + Capital Costs + Material Costs) = Accounting Profit
$1,000,000 - ($600,000 + $150,000 + $200,000) = $1,000,000 - $950,000 = $50,000.
The firm's accounting profit for the last year was $50,000.
