Q. Leary Chemical manufactures 3 chemicals: A, B and C. These chemicals are produced via 2 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 decide a daily production plan that minimizes the cost of meeting Leary Chemical's daily demands.
