Feasible Region:
Bounded vs. UnboundedThe feasible region is enclosed, or bounded, by the constraints. The maximum and minimum always occur at a vertex.
Bounded vs. UnboundedThe feasible region is open, or unbounded, and can go on forever.
Bounded ExampleGraph the following system of inequalities. Name the coordinates and find the vertices of the feasible region. Find the maximum and minimum values of this region.
Unbounded ExampleGraph the following system of inequalities. Name the coordinates and find the vertices of the feasible region. Find the maximum and minimum values of this region.
ExamplesGraph the following system of inequalities. Name the coordinates and find the vertices of the feasible region. Find the maximum and minimum values of this region.

Linear Programming—Optimization
Optimize:
7 Steps of Optimization
Step 1: Define the variable
Step 2: Write a system of inequalities
Step 3: Graph the system of inequalities
Step 4: Find the coordinates of the vertices of the feasible region.
Step 5: Write a linear function to be maximized or minimized.
Step 6: Substitute the coordinates of the vertices into the function.
Step 7: Select the greatest or least result. Answer the problem.
Linear Programming WorksheetEach week, Mackenzie can make 10 to 25 necklaces and 15 to 40 pairs of earrings. If she earns profits of $3 on each pair of earrings and $5 on each necklace, and she plan to sell at least 30 pieces of jewelry, how can she maximize profit?
