Q1. Solve the following linear programming problems by the graphical method.
A company manufactures two types of cell phones, a Basic model and a Pro model. The Basic model generates a
profit of $100 per phone and the Pro model has a profit of $150 per phone. On the assembly line the Basic phone
requires 7 hours, while the Pro model takes 11 hours. The Basic phone requires one hour and the Pro phone needs
3 hours for finishing, which includes loading software. Both phones require one hour for testing. On a particular
production run the company has available 1,540 work hours on the assembly line, 360 work hours for finishing,
and 200 work hours in the testing department. How many cell phones of each type should be produced to
maximize profit, and what is that maximum profit?
