For the tree shown in Figure 6.30, with demand weights as shown in the boxes beside each node on the tree, solve for the demand-weighted 1-median. Show the order in which you process nodes, the location of the 1-median, and compute the objective function for the optimal location.

For the tree shown in Figure 6.31

(a) Find the 1-median. Clearly indicate where the solution is.

(b) What is the objective function for the 1-median problem?
