Question: A company producing a standard line and a deluxe line of dishwashers has the following time requirements (in minutes) in departments where either model can be processed.

Standard Deluxe

Stamping 3 6

Motor Installation 10 10

Wiring 10 15

The standard models contribute $20 each and the deluxe $30 each to the profits. Because the company produces other items that share resources used to make the dishwashers, the stamping machine is available only 30 minutes per hour, on average. The motor installation production line has 60 minutes available each hour. There are two lines for wiring, so the time availability is 90 minutes per hour. Please formulate the linear programming problem (do not solve it).
