%23 50 Bree 100 100 Jeppe 50 100 50 (a) Set up and solve a system of equations to solve for the traffic flow along the middle sections of the four streets. (Assume x = traffic on the middle section of Bree, y = traffic on the middle section of Jeppe, z = traffic on the middle section of Simmons, and w = traffic on the middle section of Harrison. If the system is dependent, express your answer in terms of w, where x = x(w), y = y(w), and z = z(w).) (x, y, z, w) = (b) Is there sufficient information to calculate the traffic along the middle section of Jeppe Street? If so, what is it; if not, why not? O Yes, there is sufficient information, and the value is 50 cars. O Yes, there is sufficient information, and the value is 100 cars. O Yes, there is sufficient information, and the value is 500 cars. O No, there is not sufficient information, because the equation describing y in terms of w has no possible values. O No, there is not sufficient information, because the equation describing y in terms of w has more than one possible value. (c) Given that 300 cars per minute flow down the middle section of Bree Street, how many cars per minute flow down the middle section of Simmons? cars per minute
