Assignment 1 - Due Assignment 1 X (4) Excel - Linear Programming (1 x + https://unt.instructure.com/courses/54278/assignments/1117621?module_item_id=3280552 t 1.pdf & Down Page 3 of 3 Problem 3 (33 pt) Uncle Joe's Farms uses no less than 750 pounds of feedstuff every day. The feedstuff the use is a mixture of modified wheat and barley. Some nutritional information is shown below: FEEDSTUFF PROTEIN (LB. PER LB. OF FEEDSTUFF) FIBER (LB. PER LB. OF FEEDSTUFF) COST ($/LB) WHEAT 0.09 0.02 0.30 BARLEY 0.60 0.06 0.90 Uncle Joe's want to know what is the mix that they should use such that it contains a minimum of 25% protein and no more than 6% of fiber. They want to produce that mix at a minimum cost and they seek your help. For this problem, you will have to develop and solve a linear programming problem. For developing the model, answer the following questions a) Clearly define the variables of your problem. b) Define the objective function. c) Write the constraints. Be specific about what each constraint means. d) Write the entire model. Once you have written down your optimization problem, answer these other questions: e) (4pt) Draw the feasible region. ) (4pt) Draw two isocost lines and determine the direction of decrease for the objective function. g) (4pt) Imagine that Uncle Joe's CEO goes bananas and decides to go for a mix that maximizes costs instead. In that case, what would be the optimal solution of this problem and why? h) (11 pt) Solve the minimization problem with Excel and interpret your solution. ch O Fi P W 91 OF DII X PrtSon Home End F3 F4 F5 F6 F7 F8 F9 F10 $ o & K 4 5 6 8 9 O R T
