The revenue, in dollars, of a company that makes toy cars can be modeled by the polynomial 3x2 4x – 60. The cost, in dollars, of producing the toy cars can be modeled by 3x2 – x 200. The number of toy cars sold is represented by x. If the profit is the difference between the revenue and the cost, what expression represents the profit? 3x – 260 3x 140 5x – 260 5x 140
