Paul's Pretzels manufactures and distributes gourmet pretzels for limited retail sales. Paul has determined the "demand points" and their relative locations as follows:

Demand point	Coordinates		Demand
	x	y
A	10	10	100
B	10	20	200
C	15	10	150
D	20	10	200

a.If Paul desires to locate a manufacturing facility at the center of gravity, what would be the x and y coordinates of the facility?

b.If a facility were to be located at the center of gravity, what would be the load-distance score? (Assume rectilinear distance.)
