Solve the problem.The figure shows two intersections, labeled A and B, that involve one-way streets. The numbers and variables represent the average traffic flow rates measured in vehicles per hour. For example, an average of 600 vehicles per hour enter intersection A from the west, whereas 250 vehicles per hour enter this intersection from the north. A stoplight will control the unknown traffic flow denoted by the variables x and y. Use the fact that the number of vehicles entering an intersection must equal the number leaving to determine x and y.
A. x= 250, y = 150 B. x= 600, y = 500 C. x= 400, y = 450 D. x= 450, y = 400
