1. Formulate a linear model (clearly state decision variables, objective function, and constraints) 2. Find optimal solutions using graphical techniques as shown in class PowerPoint slides. 3. Find slack or surplus variables at each optimal solution. 4. Show your work to get all points. #3 The Kalo Fertilizer Company makes a fertilizer using two chemicals that provide nitrogen, phos- phate, and potassium. A pound of ingredient 1 contributes 10 ounces of nitrogen and 6 ounces of phosphate, while a pound of ingredient 2 contributes 2 ounces of nitrogen, 6 ounces of phos- phate, and 1 ounce of potassium. Ingredient 1 costs $3 per pound, and ingredient 2 costs $5 per pound. The company wants to know how many pounds of each chemical ingredient to put into a bag of fertilizer to meet the minimum requirements of 20 ounces of nitrogen, 36 ounces of phos- phate, and 2 ounces of potassium while minimizing cost. a. Formulate a linear programming model for this problem. b. Solve this model by using graphical analysis
