More Complex Feasible Regions

The feasible region is bounded by the following points:

2 bags of high grade and 7 bags of low grade;
3 bags of high grade and 6 bags of low grade;
5 bags of high grade and no bags of low grade; and
2 bags of high grade and no bags of low grade.

Note that all of these are feasible since they are on the boundary of the feasible region.

Exercise 5.

a)

b)

Notice that the second constraint has no effect on the feasible region, since every non-negative point that satisfies the first constraint also satisfies the second. The second constraint is redundant.
