They use two types of coffee to produce the blends: Brutte and Sagada. Let cj represent pounds of coffee i in blend j i = B, S (for Brutte and Sagada respectively) j = R, K (for RustMountain and Kanadana respectively) The shop has 170 pounds of Brutte available. Input the coefficients and the appropriate inequality sign for the constraint below: CBR + CBK + CSR + "SK ? v 170 ? = You must enter a value in every answer box for full credit. If a variable is nez ing used in your formulation, input 0 for its coefficient. Check AnswerI -|- - - w . .- Use the following network representation of a transportation problem to answer the questions that follow: 3,3 = number of units shipped from node i to node 3' Supply Demand |n formulating an LP model for this network: a. How many decision variables are required? C] b. Besides nonnegativity constraints, howr many constraints are required? C] c. The constraint for supply node 2 is: 0 532A l 93:23 + 6320 g 440 b. Besides non-negativity constraints, how many constraints are required? c. The constraint for supply node 2 is: 05X2A + 9X2B + 6X20 - 440 OT2A + 2B + X20 - 440 OX2A + X2B + X20 = 440 ON A2 + XB2 + 02 = 440 0512A + 9X2B + 6x20 = 440 d. The constraint for demand node A is: OxAl + XA2 + XA3 = 490 07XIA + 5X2A + 9X3A = 490 OXIA + X2A + X3A - 490 OXIA + X2A + X3A = 490 O7XIA + 5x2A + 9:3A
