Real-Life Linear Inequalities: Exploring Feasible Regions

A local bakery can produce a maximum of 200 loaves of bread per day. If they want to produce at least 50 loaves of whole grain bread, how many loaves of white bread can they make? Write an inequality to represent this situation and identify the feasible region.

• x + y ≤ 200, y ≥ 50; feasible region: 0 ≤ x ≤ 150, y ≥ 50.

• x + y = 200, y ≥ 50; feasible region: 0 ≤ x ≤ 200, y ≥ 50.

• x + y ≥ 200, y ≤ 50; feasible region: 0 ≤ x ≤ 100, y ≤ 50.

• x + y ≤ 150, y ≥ 50; feasible region: 0 ≤ x ≤ 100, y ≥ 50.
