Suppose that a guitar company estimates that its monthly cost is C(x) = 400x + 600x and its monthly revenue is R(x) = -0.4x +

Suppose that a guitar company estimates that its monthly cost is C(x) = 400x² + 600x and its monthly revenue is R(x) = -0.4x³ + 600x²200x + 500, where x is in thousands of guitars sold. The profit is the difference between the revenue and the cost. What is the profit function, P(x)? A. P(x) = 0.4x³ + 200x² 800x +500B. P(x) = -0.4x³ + 1000x² + 400x +500c. P(x) = 0.4x³ 200x² +800x 500D. P(x) = 0.4x³ + 200x² 800x + 500
