Rental expense = $60,000

Interest expense on capital = $5,000

Total expenses = $310,000

Opportunity cost = $30,000

Total costs = $340,000

Revenue per year = $420,000

1. The annual economic costs for the firm described above is:

= $340,000  ($310,000 + $30,000).

2. The economic profit for the firm described above is:

= $80,000 ($420,000 - $340,000).

3. To receive a normal profit the firm described above would have to:
