8.6. You have been asked to help locate a catering service in the central business district of a city. The locations of potential customers on an xy coordinate grid are P1 = (4, 4), P2 = (12, 4), P3 = (2, 7), P4 = (11, 11), and P5 = (7, 14). The expected demand is weighted as w1 = 4, w2 = 3, w3 = 2, w4 = 4, and w5 = 1. Using the cross-median approach, recommend a location for the catering service that will minimize the total weighted distance traveled to serve the customers.
