Final answer:
The economic profit for the bank is $5 million.
Step-by-step explanation:
To calculate the economic profit for the bank, you need to subtract both the explicit costs and implicit costs from the total revenues. The equation is: Economic profit = Total revenues - Explicit costs - Implicit costs. In this case, the economic profit is $35 million - $20 million - $10 million = $5 million. Therefore, the correct answer is A) $5 million.
