Question 1204894:   The accompanying figure shows the flow of downtown traffic in a certain city during rush 
hours on a typical weekday. The arrows indicate the direction of traffic flow on each one  -  way 
road, and the average number of vehicles entering and leaving each intersection per hour 
appears beside each road. Fifth and Sixth Avenues can handle up to 2000 vehicles per hour 
without causing congestion, whereas the maximum capacity of each of the two streets is 1000 
vehicles per hour. The flow of traffic is controlled by traffic lights installed at each of the four 
intersections. 
(a) Set up the system of equations that would model this problem. 
(b) Solve the system of equations and write the answer in parametric form. Place restrictions 
on the parameter. 
(c) Find two possible flow patters that would ensure that  
there is no traffic congestion.
