PROBLEM 23 A large construction company undertook computerization items to equip a ministry with the PC terminal units. It was agreed to supply 150 units next October and 225 units in November. Working an eight hour shift, the manufacturer can only produce 160 terminal units per month. Extending working hours with two hours overtime, it is possible to construct 30 additional units per month, with an additional unit cost of 20. The terminal units can be stored at a monthly cost of 3 per unit. The cost of producing each unit of PC is constant, regardless of the month of construction. Formulate the model (the initial table) in order to find out the production schedule, which minimizes the total cost
