QUIZ LP Formulation

1. ACME Co. is a manufacturer of X’s which they sell to OR/MS teachers to be used as variables. For this week they intend to manufacture two types of X’s, namely, X1’s & X2’s. The profit contribution for each unit of X1 & X2 are \$4 and \$5, respectively. Mr. Loony, the manager of ACME, found out that his available supply of raw material 1 (RM1) and raw material 2 (RM2) are 18 units and 24, respectively. Each unit of X1 will require 3 units of RM1 and 3 units of RM2 while each unit of X2 will require 2 units of RM1 and 4 units of RM2. Weekly demand for X1 is about 5 units while that for X2 is about 7 units. Plant capacity of ACME Co. is 6 for X1 and 5 for X2. Formulate an LP model (objective function & constraints) than can be employed to solve for the optimal product mix.
