Final answer:
The accounting profit can be calculated by subtracting the explicit costs from the revenue. In this case, the accounting profit is $60,000.
Step-by-step explanation:
The accounting profit can be calculated by subtracting the explicit costs from the revenue. In this case, the explicit costs are $40,000 and the revenue is $100,000. So, the accounting profit would be $100,000 - $40,000 = $60,000. Therefore, option b) $60,000 is the correct answer.
