Can someone help me with this linear programming?

Aviation Electronics produces three types of switching devices.Each type involves a two-step assembly operation.The assembly times are shown in the table below.

Assembly Time per Unit

Station #1 Station #2

Model A 2.5 minutes 3.0 minutes

Model B 1.8 minutes 1.6 minutes

Model C 2.0 minutes 2.2 minutes

Each workstation has a daily working time of 7.5 hours.Manager Bob Parkes wants to obtain the greatest possible profit during the next five working days.Model A yields a profit of $8.25 per unit, Model B a profit of $7.50 per unit, and Model C a profit of $7.80 per unit.Assume the firm can sell all it produces during this time but it must fill outstanding orders for 20 units of each model type.

Formulate the linear programming model of this problem.Solve the model to show the maximum amount of profit possible given the constraints outlined above.
