Leary chemical manufactures three chemicals: a, b, and c. these chemicals are produced via two production processes: 1 and 2. running process 1 for an hour costs $4 and yields 3 units of a, 1 of b, and 1 of c. running process 2 for an hour costs $1 and produces 1 unit of a and 1 of b. to meet customer demands, at least 10 units of a, 5 of b, and 3 of c must be produced daily. graphically determine a daily production plan that minimizes the cost of meeting leary chemical’s daily demands.
