1.) Help the Amazon technology support staff to minimize their total costs. Each support staff person works five consecutive days followed by the next two off, and this schedule is repeated every week (each person has the same days off each week). Amazon can also hire students to support the staff needs. If hired, students must work Monday through Friday straight and have the weekend off. There must be at least two non student staff members working each day. There is also an Amazon rule that at least 60% of all staff (including student workers) should have Sundays off. Student workers cost $20 /hour and regular support staff costs $40 hour. A workday is 8 hours long. The number of staff needed each day is below a.) Formulate mathematically this L.P model: state the decision variable, objective function, and list all the constraints. b.) Solve the model using Excel Solver. Provide an image of your model, solver sereen, and report the optimum solution
