Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures cell phones can be modeled by the polynomial 2⁢x2+55⁢x+10. The cost, in dollars, of producing the cell phones can be modeled by 2⁢x2−15⁢x−40. The variable x represents the number of cell phones sold. What expression represents the profit, and what is the profit if 240 cell phones are sold?
