Suppose that the revenue R, in dollars, from selling x cell phones, in hundreds, is R(x) = - 1.4x + 337x. The cost C, in dollars, from selling x cell phones, in hundreds, is C(x) = 0.09x2 – 3x² + 55x + 650. (a) Find the profit function, P(x) = R(x) - C(x).
(b) Find the profit if x = 18 hundred cell phones are sold.
(c) Interpret P(18).
