Solve the problem.During rush hours, substantial traffic congestion is encountered at the intersections shown inthe figure. The arrows indicate one-way streets. As the figure shows, 700 cars per hour come down to intersection A, and 400 cars per hour come down to intersection A. x of these cars leave A on and w cars leave A on 400 in 900 out 800 out 500 in 5th Street 6th StreetThe number of cars entering intersection A must equal the number leaving, so that or By writing an equation representing the traffic entering and leaving each of the intersections A, B, C, and D, obtain a system of four equations. Solve the system using w as the parameter and use your answer to determine the largest and smallest possible values for the number of cars leaving intersection D on R Street.
