2. Assume that the total benefit resulting from a continuous decision, Q, is B(Q) = 20Q - 2Q2 and the corresponding total cost is C(Q) = 4 + 2Q2. A. Determine the optimal level of Q that maximizes total benefit the values of maximum total benefit. (5 points) B. Determine the optimal level of Q that maximizes net benefit and the value of maximum net benefit. (5 points) 3. Consider the cost function: C(X) = 0.004X3 + 20X + 1000. A.
