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
