Would you like to try solve the fertilizer example using LP Grapher or manually (by identifying the feasible region and checking which corner point is the best solution)? Let x1 = bags of Super-Gro x2 = bags of Crop-Quick Minimize Z = $6*x1 + $3*x2 (total cost) subject to: 2*x1 + 4*x2 >= 16 (nitrogen) 4*x1 + 3*x2 >= 24 (phosphate) x1, x2 >= 0 (nonnegativity)
