These are all parts to the same problem

Please do not copy from other posts. I have had this problem too many times with this service and I will be contacting support if I see this happen.

The next three questions are based on the following: The network diagram below represents the shipment of peaches from 3 orchards (Nodes 1, 2 and 3) through two warehouses (Nodes 4 and 5) to the two farmers markets (Nodes 6 and 7). The supply capacities of the 3 orchards are 800,500 and 400 respectively. The farmer market demands are 700 each. The numbers on the arcs represent the cost of shipping 1 pound of peaches along that arc. Let Xij represent the amount of peaches shipped from node i to node j. Using these decision variables, as well as the cost, supply and demand values, we can write a transshipment problem to minimize the total cost of shipment. 20. Which of the following represents the constraint for Orchard 3? None of the above. x34+x35+x23
