Leary Chemical manufactures three chemicals: A, B, and C. These chemicals are produced via two production processes: Process 1 and Process 2. Running Process 1 for an hour costs $4 and yields 3 units of A, 1 unit of B, and 1 unit of C. Running process 2 for an hour costs $1 and it produces 1 unit of A and 1 unit of B. To meet the customer demands, at least 10 units of A, 5 units of B, and 3 units of C must be produced daily. Graphically determine a daily production plan that minimizes the cost of meeting Leary Chemical's daily demands.
