III) Please formulate the following Linear programming problems from the Textbook and solve then using either Matlab or GAMS. (16 points) The objective functions and constraints formulated should be provided prior to notifying the solutions from Matlab/GAMS (No need to solve by Simplex or Graphical method, even if the textbook problem mentions it) a) Problem\#2.2 (Textbook - Diwekar) 2.2 A refinery has two crude oil materials with which to create gasoline and libe oil: 1. Crude A costs 828/bbl and 18,000bbl are available. 2. Crude B costs $38/bbl and 32,000bbl are available. The yield and sale price per barrel of the products and the associated markets are shown in Table 2.18. How much crude A and B should he used to maximize the profit of the company? Table 2,18. Yeld and sule prices of products, How would the optimal solution be affected if 1. The market for lube oil increased to 14,000 . bbl 2. The cost of crude A decreased to $20/bbl
