- The document discusses optimizing production of three tomato products - whole canned tomatoes, tomato juice, and tomato paste - given constraints around available quantities and qualities of tomatoes. - It presents a linear programming model to maximize total contribution (profit) by determining the optimal allocation of grade A and B tomatoes to the three products, while adhering to demand, quality, and quantity constraints. - Running the model for the contracted 3 million pounds of tomatoes results in a gross profit of $45,340, whereas procuring an additional 80,000 pounds could increase profit by $424 to $45,764.
