A vertex of a feasible region does not always have whole-number coordinates. Sometimes you may need to round coordinates to find the solution. Using the objective function and the constraints at the right, find the whole-number values of x and y that minimize C . Then find C for those values of x and y.
C=6x+9y
x+2y≥50
2x+y≥60
x≥0 , y≥0
