The feed mill pays a farmer 6930.00 for the 1st delivery. $5475.00 for the 2nd delivery and $8879.50 for the third delivery. the table shows the # of bushels included in each delivery. use that table to write and solve a system of equations to find the price per bushel that the farmer received for each crop.
delivery: corn } wheat ] soybeans
1st: 900 540 360
2nd: 1125 150 225
3rd: 860 645 645

so far my equations are:
900x + 540y + 360z=6930 x=corn
1125x + 150y +225z=5475 y = wheat
860x + 645y + 645z=8879.50 z = soybeans
