4. See the following Management Scientist output. In this problem, we are trying to determine the optimal number of rolls of four types of fabric (1, 2, 3, and 4) to produce. Note that the third constraint concerns the available quantity of a certain chemical resin used for each type of fabric, the fourth constraint concerns the available quantity of polyester, and the final two constraints are imposed to ensure that we will incur a $200 penalty if we produce at least 600 units of Types 2 and 4 (since this will require us to redeploy an additional production line). A. Which constraints are binding? (2) _________ B. Which constraint would we prefer to see relaxed? (2) ________ C. Nora in Accounting realized that the profit associated with Type 1 fabric should be $8.00/unit. Will this have an effect on the optimal solution? (2) Yes_____ No______ D. If the availability of the chemical (third constraint) were 15,000, what effect would this have? (2) None____ Increase the optimal profit______ Decrease the final profit
