PRODUCTION. Klone Computer (see problems 28, 29) is making one last production run of its KCU and KCP computers before introducing its new line of models, which includes CD-ROM drives, utilizes faster CPUs and floppy disk drives, and has larger hard disk drives. Because this is the last run of “old technology” machines, Klone’s net profit per computer has been reduced from $100 and $250 to $75 and $105 for KCU and KCP models, respectively. The following table summarizes the resource requirements and unit profits for each computer model and the resources available for this final production run of these models.

29.  MANUFACTURING. For the Klone Computer problem (problem 28):

a. Suppose the unit profit for the KCU model were increased to $150 per unit. Does the optimal solution change? Does the total profit change? Suppose the profit for the KCU model could be increased to $200 per unit. Does the optimal solution change? Does the total profit change?

 b. The unit profit coefficients took into account the $50 per unit cost to Klone of the floppy disk drives. Klone has negotiated a deal with another company to purchase floppy disk drives at $35 each. Will the optimal solution change? If so, what will be the new optimal profit?

c. Suppose the constraint requiring the production of at least 300 KCU models were eliminated. Determine the new optimal solution.
