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, 600 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 
-4.0px;" /> 400 in 600 out 
900 out 400 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.
A. (400 - w, 1100 + w, 1400 - w, w)
B. (1000 - w, 500 + w, 1400 - w, w)
C. (1000 - w, 1100 + w, 500 - w, w)
D. (1000 - w, w - 500, 1400 - w, w)
