The figure below shows a network of one way streets. The direction the traffic it flowing is indicated with the arrows and the values represent the average number of vehicles per hour entering or exiting the intersection. a) Set up a system of linear equations that represents this scenario, with unknown flow rates as your variables. b) Solve the system form part a) Write your solutions here attach work. c) Suppose there needs to be construction on the road from A to B and traffic needs to be restricted. What is the minimum flow that is required to keep traffic flowing on all roads
