The Davis national drugstore chain prefers to operate one outlet in a town that has four major market

segments. The number of potential customers in each segment along with the coordinates are as

follows:

Which would be the best location by the center$-$of$-$gravity method?

Problem $2$:

For the Davis drugstore chain in problem $1,$ suppose that after five years, half the customers from segment $1$ are expected to move to segment $2.$ Where

should the drugstore shift, assuming the same

criteria are adopted, and the chain still use center of gravity method?
