Final answer:
The firm's accounting profit was $115,000. The economic profit was $55,000.
Step-by-step explanation:
Accounting Profit:
To calculate the accounting profit, we subtract the explicit costs from the revenue.
In this case, the revenue is $200,000 and the explicit costs are $85,000.
Therefore, the accounting profit is $115,000.
Economic Profit:
To calculate the economic profit, we need to consider the opportunity cost of using the firm's own land instead of renting it.
The opportunity cost is the $30,000 annual rent.
Since the firm owns the land, this cost is not included in the explicit costs.
Therefore, the economic profit would be $85,000 (accounting profit) minus $30,000 (opportunity cost of land).
This results in an economic profit of $55,000.
Thus, accounting profit was $115,000 and the economic profit was $55,000.
