Mr. watford owns two car dealerships. his profit from the first can be modeled with the polynomial c 3 − c 2 + 2c − 100, where c is the number of cars he sells. mr. watford’s profit from his second dealership can be modeled with the polynomial c2 − 4c − 300. a. write a polynomial to represent the difference of the profit at his first dealership and the profit at his second dealership. b. if mr. watford sells 45 cars in his first dealership and 300 cars in his second, what is the difference in profit between the two dealerships?
