3. Applications of the Anti-derivative: The ACME company plans to commercialize the Aereo-3 fans. The marketing department has developed the following equations:

A. Find the Profit equation (Revenues R(x)) of the following marginal profit equation. Assume as constant C = $4,000 R'(x) = -0.04x+900

B.Find the cost form of the following marginal cost form. Assume fixed costs of $1,000 (C=1000) C'(x) = 0.02x + 600 C. Determine the equation for total profit (Profit P(x)). D. For the manufacture of x = 5000, what will be the total Profit?
