Joe's Window Washing is searching for an ideal location to support its Houston customers. It washes windows in three neighborhoods. Plotting the center of each neighborhood on an X-Y Grid yielded the following results: Neighborhood 1: X=3 Y=6 POPULATION = 10 Neighborhood 2: X=4 Y=1 POPULATION = 20 Neighborhood 3: X= 5 Y= 2 POPULATION = 30 Using the Weighted Center of Gravity Method, what are the X-Y coordinates for the optimal location? IM- WX Weighted X coordinate = X* = where: Weighted Y coordinate = y* = IM- IM- WY Wi (X, Y) = position of demand point i W;= weighting factor for demand point i
