Suppose a shoe company estimates that its monthly cost is C(x) = 300x2 + 200x and its monthly revenue is
R(x) = -0.523 + 900x2 – 500x + 400, where x is in thousands of pairs
of shoes sold. The profit is the difference between the revenue and the cost.
What is the profit function, P(x)?
A. P(x) = 0.5x3 + 60022 – 700x + 400
B. P(x) = 0.5x3 – 600x2 + 700x - 400
C. P(x) = -0.5x3 + 600x2 – 700x + 400
D. P(x) = -0.5x3 + 1200x2 – 300x + 400
