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).

a

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
