Example 5

Determine the optimal production plan for Irwin and the maximum level
of contribution that Irwin can earn.

Solution

The optimal production point occurs where the testing time constraint meets
the constraint on x’s sales (there a number of ways to determine this).

This means that x = 300. This value can be entered into the equation for
testing time to determine y:

= (120 × 300) + 180y = 52,500
