2. Name the worksheet Purewal. 3. Purewal Inc. uses three machinists to produce engines. The resources used to produce an engine are outlined in the table below. The contribution margin per engine and demand is also outlined in the table below. The three machinists make up 600 labour hours. Purewal can secure a total of 500 machine hours. It must produce at least 20 engines by Machinist 1. Assuming there are no capabilities for Purewal to produce part engines, design a simplex linear solver model to maximize profits for Purewal. 2.
