One acre of land yields an average of 1.5 tons of alfalfa and 2.2 tons of barley. The wheat yield is approximately 50 bushels per acre. Young's best estimate is that she can sell wheat at a net profit of $2 per bushel, alfalfa at $40 per ton, and barley at $40 per ton. The wheat yield is approximately 50 bushels per acre. Write the objective function and constraints for the linear programming problem if we want to maximize the profit? What is the solution to this linear programming
