- (40 pts) Bright Future (BF) Company is producing two different laptops: modelX, model modelX brings $200, model brings $250 profit for BF company. Demands for modelX and model are forecasted to be 200 and 100 during the month. Production processes for either model are assembly, polishing, and packaging, modelX consumes 1.5 hours of assembly time per unit, 0.3 hour of polishing, and 0.2 hour of packaging. Corresponding values per unit of modelZ are 2, 0.5, and 0.4. There are 500 hours of assembly time, 200 hours of polishing, and 150 hours of packaging time available over the next month. The problem's LP model and AMPL output are given (main constraints are named in order c1,c2....,c5; x1 is used for modelX, X2 is used for modelz): maximize 200x: + 250xz subject to *4 2 200 *2 2 100 1.5x2 + 2x2
