Before beginning this exercise, the group needs to read and solve Exercise 244. a. A political group is planning a demonstration on 95th Street between 113th Place and 117th Court for 5 p.m. Wednesday. The problem becomes one of minimizing traffic flow on 95th Street (between 113th and 117th) without causing traffic tie-ups on other streets. One possible solution is to close off traffic on 95th Street between 113th and 117th (let x₆
= 0). What can group members conclude about x₇
under these conditions? b. Working with a matrix allows us to simplify the problem caused by the political demonstration, but it did not actually solve the problem. There are an infinite number of solutions; each value of x₇
we choose gives us a new picture. We also assumed x₆
was equal to 0; changing that assumption would also lead to different solutions. With your group, design another solution to the traffic flow problem caused by the political demonstration.
