Step-by-step explanation:
The Cushman Company had total sales of $842,000. Therefore, the answer to the question 'What was the total sales amount' is option 1, which is $842,000.
To find the firm's accounting profit, we subtract the explicit costs (labor, capital, and materials) from the total revenues. The calculation is as follows:
Accounting profit = Total revenues - Explicit costs
Accounting profit = $1,000,000 - ($600,000 + $150,000 + $200,000)
Accounting profit = $1,000,000 - $950,000
Accounting profit = $50,000
