E20.30 (appendix) Linear programming; formulate and solve graphically: manufacturer LO 20.10 The Jersey Chemical Company manufactures two industrial chemical products, called Zanide and Kreolite. Two machines are used in the process, and each machine has 24 hours of capacity per day. The following data are available: Zanide Kreolite $36 $42 $28 $28 Selling price per drum Variable cost per drum Hours required per drum on machine I Hours required per drum on machine II 2 hours 2 hours 1 hour 3 hours The company can produce and sell partially full drums of each chemical. For example, a half drum of Zanide sells for $18. Required: 1. Formulate the product mix problem as a linear program. 2. Solve the problem graphically. 3. What is the value of the objective function at the optimal solution
