Final answer:
The estimated profit margin for the upcoming year cannot be determined without information about expected expenses.
Step-by-step explanation:
The estimated profit margin for the upcoming year can be calculated by subtracting the expected expenses from the expected revenue. The profit margin is the profit as a percentage of the revenue. In this case, the profit margin would be ($1,160,000 - expenses) / $1,160,000.
However, the question doesn't provide information about the expected expenses, so we cannot calculate the profit margin.
Therefore, we cannot determine the correct answer from the given options.
