Consider the following example: Dairy-Day produces two different types of dairy products: milk & vogurt. Both products undergo two processes: "Processes 1 & 2". To proceed with production, Dairy-Day has at least 21 hours for process I, and at least 25 hours for process 2. Milk requires an hour in process I, and 3 hours in process 2. On the other hand, yogurt requires 2 & 3 hours respectively in processes 1& 2. The cost of producing a bottle of milk is 84 while it costs $7 to produce a bottle of yogurt Formulate the above "Primal LP model then answer the following questions. The above "Primal LP" Model is assigned LLL Dual variables two: Y1 & Y2 two, Xi & X2 three, X1, X2,8 X3 three Y1, Y2, & Y3 * The "Dual" objective function is written as minimize w = 21y1 + 25y2 minimize z = 6x1 + 4x2 maximize w = 21y1 + 25y2 O maximize z = 6x1 + 4x2 The first "Dual" constraints is written as O x1 + 2x2 s 21 O y1+ 3y2 54 O y1 + 3y2 2 4 O x1+ 2x2 221 The 2nd "Dual" constraint is written as O 3x1 + 3x2 25 Coefficients of Slacks in the Optimal Dual LP model - * O optimal value of the slack variables in the "Primal LP Model" optimal value of the decision variables in the "Primal LP Model O Coefficients of Slacks in the Optimal Primal LP model O coefficients of the decision variables in the optimal "Primal LP Model Rar NAVE Giann fan
