Please try and make some answers from this question because that's all I have from the question.. Just some ideas to start from

Question 2 (12 marks) The following table shows lower and upper limit arc capacities as well as a cost of flow (per unit). Draw the network diagram and formulate a LP model that will ensure the following. A total of 5 units should flow from the source node to the sink node.
