What expression represents the profit, and what is the profit if 240 cell phones are sold?
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 2x2 +
55x + 10. The cost, in dollars, of producing the cell
phones can be modeled by 2x2 - 15x - 40. The
variable x represents the number of cell phones sold.
O40x - 30; $2,400
040x - 30; $9,570
O 70x + 50; $16, 850
