SeedMart mixes mixes two types of seeds into a blend. Each type of seed has been rated ( per pound) according to its shade tolerance , ability to stand up to traffic, and drought resistance, as shown in the table. Type A seed costs $1 and Type B seed costs $2. The blend needs to score at least 300 points for shade tolerance, at least 400 points for traffic resistance, and at least 750 points for drought resistance, how many pounds of each seed should be in the blend to minimize costs (provide Excel sheet) . What is the objective function value? Using the optimal solution, demonstrate the calculation of the objective function value .
