1. (25 points) Canadian tire located in waterloo is supposed to receive shipment of same product from Hamilton and Toronto. Shipment from Hamilton cost $0.2 per unit and shipment from Toronto costs $0.25 per unit. Monthly demand for that product at that Canadian tire location is equal to 5000 units. No more than 4000 units per month can be shipped from Hamilton and no more than 3000 units per month can be shipped from Toronto. Develop a mathematical model that minimizes the cost of shipment of that product per month for Canadian Tire assuming that the number of units ordered per month are the number of units sold per month.
