This cattle feed is made by combining two ingredients, Alfalfa and Barley. Alfalfa is a plant of the pea family grown primarily for forage. Barley is a cereal crop. They have the following characteristics: Cost (kg) Availability (kg) Pmtein quality per kg 17.7% 12.3% DE ner k- 2.60 3.65 Use the following decision variables to formulate the linear programming model with 9 constraints to maximize profit. AR = kilograms of Alfalfa in Regular AP = kilograms of Alfalfa A in Premium BR = kilograms of Barley in Regular Bp = kilograms of Barley in Premium Hints: To formulate the OFC { Prot = Price - Cost) you need only consider the cost of the Alfalfa and Barley put into either of the two different types of feed. AR + 3;; is the kilograms of regular feed. AR + AP is the kilograms of Alfalfa. Percentages can be converted to proportions in the constraints
