A county wants to build one$$centrally$-$located processing

facility to serve the$$county$\text{'}$s four recycling$$drop$-$off

locations. The four$$drop$-$offs have characteristics as given

in the table below.Location$$X$-$coordinate$$Y$-$coordinateTonnage$$Drop$-$off point A$1810$Drop$-$off point B$6735$Drop$-$off point C$6225$Drop$-$off point D$4730$What is the approximate center of gravity of these
