Question 1: A Chemical Laboratory 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, l of B: and 1 of C. Running process 2 for an hour costs $1 and produces 1 unit of A and l of B. To meet customer demands, at least 1D units of A: 5 of B, and 3 of C must he produced daily. Graphically determine a daily production plan that minimizes the cost of meeting Laboratory's daily customer demands
