A county is going to build two hospitals. There are nine cities in which the hospitals can be built. The number of hospital visits per year made by people in each city and the x-y coordinates of each city are listed in the file P06_83.xlsx. The county’s goal is to minimize the total distance that patients must travel to hospitals. Where should it locate the hospitals? (You will need to determine the distance between each pair of cities. An easy way to do this is with lookup tables.)
