Final answer:
After subtracting the total expenses of $950,000 (labor, capital, materials) from the sales revenue of $1 million, the firm's accounting profit is $50,000.
Step-by-step explanation:
To ascertain the firm's accounting profit, we need to subtract all its expenses from its sales revenue. Given that the firm had sales revenue of $1 million last year and incurred expenses of $600,000 on labor, $150,000 on capital, and $200,000 on materials, the calculation is as follows:
Total Expenses = Labor + Capital + Materials
= $600,000 + $150,000 + $200,000
= $950,000
Subtracting the total expenses from the sales revenue, we get:
Accounting Profit = Sales Revenue - Total Expenses
= $1,000,000 - $950,000
= $50,000
Therefore, the firm's accounting profit is $50,000.
