how to find the optimal solution in excel solver decisions variables. (3 marks) Type A is x Type B is y Function is to minimize the cost of the blend while meeting the constraints of performance C = 1x +2y b. Formulate the constraints in terms of the decision variables. (6 marks) Constraints are: Shade tolerance 1x+1y 300 Traffic Resistance 2x+1y 400 Drought Resistance 2x+5y 750 Also, x and y should not be negative so the following constraints X, y0 c. Draw the graph with 3 constraint lines and the object line and annotate the graph to identify the optimum. (4marks) 400 -2x = 300 -x 400 -300 =2x -x 100=x Y=300-100= 200 Shade tolerance and traffic resistance (100,200) 1500-5x =750-2x 1500-750=5x-2x 750=3x 750/3=x X=250 Y=300-250=50 Shade tolerance and drought resistance (250,50) 2000-10x =750-2x 2000-750=10x-2x 1250=8x X=1250/8 156.25 y=400-2(156.25) =400-312.5 = 87.5 Traffic resistance and drought resistance (156.25,87.5) d. How many pounds of each seed should be in the blend? (2 marks)
