Revisit the copying service in the class example $($all the details are given below, you don't have

to search the slides. If you are curious, this example was part of Chapter $8$ part $1).$ The locations

of the four customers were respectively, $(1,2),(2,3),(3,5),(4,1).$ Assume that over the years, the

monthly demand from the four customers has increased to the following weights: w$1=7,$ w$2=$

$9,$ w$3=5,$ w$4=7.$ If we previously located the copying service at point $(2,2),$ should we now

consider relocation?
