Darnell and Stephanie work for competing refreshment stand companies. Darian's profit can be modeled using the polynomial 2c² - 7c - 200, where c is the number of items sold. Stephanie's profit can be modeled with the polynomial c² + 8c - 100. Write a polynomial to represent the difference between their profits.

• c² -15c - 100
• 3c² -c - 300
• c² +15c + 300
• 3c² -15c - 100
