A computer manufacturer makes a standard model and a gaming model. Each standard computer requires 2 labor-hours from the assembly department and 5 labor-hours from the programming department. Each gaming computer requires 4 labor-hours from the assembly department and 5 labor-hours from the programming department. The maximum labor-hours available per day in the assembly department and the programming department are 48 and 80, respectively. The company makes a profit of $380 on each standard computer and $620 on each gaming computer.

Let x = standard computer
Let y = gaming computer

Then, 2x + 4y < 48
and 5x + 5y < 80.

The graph of these functions is shown to the right. Since a negative number of computers cannot be produced, both x and y have to be greater than zero.

Profit function:
P = $380x + $620y
