Sоlve the prоblem.During rush hоurs, substаntiаl trаffic congestion is encountered at the intersections shown inthe figure. The arrows indicate one-way streets. As the figure shows, 300 cars per hour come down to intersection A, and 800 cars per hour come down to intersection A. x of these cars leave A on and w cars leave A on 800 in 800 out 500 out 200 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.
