Suppose a shoe company estimates that its monthly cost is C(x) = 300x2 + 2002 and its monthly revenue is
R(x) = -0.52% + 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) = -0.52% + 120022
300x + 400
O B. P(x) = -0.52% + 600x2 – 700x + 400
c. P(x) = 0.52% – 600x² + 700x 400
O D. P(x) = 0.57% + 600.72
7000 + 400
