Question 2) develop an objective function that would maximize total profit.
Question 3) Whole Foods needs at least 1,000 units of beets. The Ames supplier can supply no more than 900 units. Develop constraints for these conditions. Solve the given numerical problem and illustrate step by step calculation.
