Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x^2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x^2 - 160x + 300. The variable x is the number of the televisions sold. If 150 televisions are sold, what is the profit?
