Extracted text: 9. Suppose we modify the production model in Section 1.3 to obtain the following mathe- matical model: Max 10x st. ax s 40 x20 where a is the number of hours of production time required for each unit produced. With a = 5, the optimal solution is x = 8. If we have a stochastic model with a = 3, a = 4, a = 5, or a = 6 as the possible values for the number of hours required per unit, what is the optimal value for x? What problems does this stochastic model cause?
