Final answer:
The profit function for the football team is given by the equation Profit = 20x - 8x - 500, where x represents the number of calendars sold.
Therefore, the correct answer is A) Profit = 20x - 8x - 500.
Step-by-step explanation:
The profit function for the football team can be calculated as follows:
Profit = Total Revenue - Total Cost
Total Revenue = Selling Price * Quantity
Total Cost = Printing Cost + Sales Expenses
Given that the selling price of each calendar is $20 and the printing cost is $8 per calendar, we can write the profit function as:
Profit = 20x - 8x - 500
