Earl’s Biking Company manufactures and sells bikes. Each bike costs $40 to make, and the company’s fixed costs are $5000. In addition, Earl knows that the price of each bike comes from the price function, p(x) = 300 -2x.   (x = quantity produced) Determine:

R = 300x - 2x2    Answer

 2. The company’s expense function, E(x). (30%)

 3. The company’s profit function, P(x)
