The revenue, in dollars, of a company that produces jeans can be modeled by 2x2 + 17x – 175. the cost, in dollars, of producing the jeans can be modeled by 2x2 – 3x – 125. the number of pairs of jeans that have been sold is represented by x. the profit is the difference between the revenue and the cost, 20x – 50. if 75 pairs of jeans are sold, what is the company’s profit?
