Recall the blend example from lecture. The parameters have changed, but the story remains essentially the same. An oil company has 3 components (A, B, and C) which it mixes to create 3 grades of motor oil (Super, Premium, and Extra). Let xij represent the number of barrels of component i used in grade j, where i is one of {A,B,C}, and j is one of {S,P,E} for Super, Premium, and Extra, respectively. The oil company needs to decide how many barrels of each component to put into each grade of motor oil to maximize its profits. If there are 100 barrels of component A, 200 barrels of component B, and 300 barrels of component C available to the oil company, and they want to produce at least 100 barrels of each grade of motor oil, what is the resource constraint for component B in standard form? xBS+xBP+xCE>=100xAS+xBS+xCE=0 0.4 A +0.6BE+0.4[CE=0 Suppose that each barrel of component C costs $20, and each barrel of Premium sells for $50. What is the coefficient on xCP in the objective function? 20 30 50 80
