Question

!!Help Please!! A magazine company estimates that its monthly cost is

C ( x ) = 700x^2 + 400x and its monthly revenue is R ( x ) = − 0.4 x^3 + 900x^2 − 200x + 600, where x is in thousands of magazines sold. The profit is the difference between the revenue and the cost. What is the profit function, P(x)?

Answer 1

P(x) = -0.4x^3 +200x^2 -600x +600

Explanation:

The profit is the difference between the revenue and the cost.

P(x) = R(x) -C(x)

P(x) = (-0.4x^3 +900x^2 -200x +600) -(700x^2 +400x)

P(x) = -0.4x^3 +200x^2 -600x +600
