If the profit is the difference between the revenue and the
cost, what expression represents the profit?
the revenue, in dollars, of a company that makes toy cars
can be modeled by the polynomial 3x2 + 4x – 60. the cost,
in dollars, of producing the toy cars can be modeled by 3x
-- x + 200. the number of toy cars sold is represented by x.
3x – 260
3x
3x + 140
5x – 260
5x + 140
