(12 points) Suppose that a certain function P(x) gives the net profit in dollars due to selling a units. Suppose also that P(350) = 1000 and that P'(350) = 20. Determine if each of the following statements are true or false. Be able to provide an explanation for your answer. ? v 1. If P'(450) is negative, and if you are currently selling 450 units, you can know for sure that selling more units will increase the total profit ? 2. If P(450) is positive, and if you are currently selling 450 units, you can know for sure that selling more units will increase the total profit ? 3. If P'(450) is positive, and if you are currently selling 450 units, you can know for sure that selling more units will increase the total profit ? 4. Selling 350 units results in a profit of 1000 dollars. ? 5. When you are selling around 350 units, selling more units will change the total profit by 1000 dollars for each additional unit. ? 6. If P'(450) is negative, and if you are currently selling 450 units, you can know for sure that selling more units will decrease the total profit Note: You can earn 30% partial credit for 2 - 3 correct answers, and 60% partial credit for 4 - 5 correct answers. preview answers Problem 7.

(16 points) Suppose that you are planning on starting a 3D printing business. 1. Suppose that the price function is given by price per unit p = -3x2 + 60x + 325. Write down an equation for R(x), the revenue from selling a units. 2. Your top choice printer has a fixed cost of 100, and that the plastic costs $325 per unit produced. Write an equation for C(x), the cost of producing a units. 3. Find the profit function. 4. Find the marginal profit function. 5. Use the marginal profit function to approximate the profit of the 11th unit. 6. Use the marginal profit function to find the exact profit from the 11th unit.
