(By Theorem 1) In the above example, the corner points (vertices) of the bounded (feasible) region
are: O, A, B and C and it is easy to find their coordinates as (0, 0), (20, 0), (10, 50) and
(0, 60) respectively Let us now compute the values of Z at these points We have
*
A corner point of a feasible region is a point in the region which is the intersection of two boundary lines
