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.
what expression represents the profit, and what is the profit if 240 cell phones are sold?
a)40x – 30; $2,400
b)40x – 30; $9,570
c)70x + 50; $16, 850
d)70x + 50; $28,800
