A manufacturer of stamped metal auto parts has four parts factories in one city at the
location coordinates shown below. Each coordinate unit represents a city block (roughly
100 meters). The yearly demand at each factory is also given.
Management has decided to build a new sheet metal mill, to supply these factories, at a
location central to these plants. What should be the map coordinates of the new plant?
On the grid below, graph the locations of the four parts factories and the proposed sheet
metal mill.
