Pullman Farm Supply has just received an order for precisely 10,000 pounds of chicken feed. The farmer has specified that the feed meet minimum percentage requirements for protein, carbohydrate, fat and vitamins. Pullman Farm can blend four different feeds to produce the required mix. The farmer would like to pay the lowest possible price for the feed. The data for the problem is summarized in the following table. Note that the numbers in the table (except for the costs) are percentages, that is, Feed 1 is 9% protein, and the final mix must be at least 12% protein. Nutrient Feed 1 Feed 2 Feed 3 Feed 4 Minimum Required % in Mix Protein 9 21 15 13 12 Carbohydrate 20 12 32 14 21 Fat 17 18 16 19 18 1 1.5 0.4 0.8 2 Vitamin Cost/1,000 lbs $550 $650 $450 $520 Let Xi = pounds (NOT thousands of pounds) of feed i used in the mixture. Formulate the complete linear program for this problem. Then answer the questions below. What is the coefficient of X2 in the objective function? [Choose ]
