Hurley Company produces two industrial cleansers, Pocolimpio and Maslimpio, that use the same liquid chemical input. Pocolimpio uses two quarts of the chemical for every unit produced, and Maslimpio uses five quarts. Currently, Hurley has 6,000 quarts of the material in inventory. All of the material is imported. For the coming year, Hurley plans to import 6,000 quarts to produce 1,000 units of Pocolimpio and 2,000 units of Maslimpio. The detail of each products unit contribution margin is as follows:
Hurley Company has received word that the source of the material has been shut down by embargo. Consequently, the company will not be able to import the 6,000 quarts it planned to use in the coming years production. There is no other source of the material.
1. Compute the total contribution margin that the company would earn if it could import the 6,000 quarts of the material.
2. Determine the optimal usage of the companys inventory of 6,000 quarts of the material. Compute the total contribution margin for the product mix that you recommend.
3. Assume that Pocolimpio uses three direct labor hours for every unit produced and that Maslimpio uses two hours. A total of 6,000 direct labor hours is available for the coming year.
a. Formulate the linear programming problem faced by Hurley Company. To do so, you must derive mathematical expressions for the objective function and for the material and labor constraints.
b. Solve the linear programming problem using the graphical approach.
c. Compute the total contribution margin produced by the optimalmix.
