After this worksheet you can
Check feasibility against constraints.Write objective functions.Write resource constraints.Understand where linear-programming optima occur.

🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4

1Constraint 4x + 5y ≤ 100: is (15, 5) feasible?
2Constraint 4x + 5y ≤ 100: is (20, 10) feasible?
3$20/unit of A and $35/unit of B: the objective is:
4In linear programming, the optimum occurs at:

🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11

5A point satisfying all constraints is .
64(15) + 5(5) = .
7Constraint: 4x + 5y ≤ 100. Is (15, 5) feasible?
8Constraint: 4x + 5y ≤ 100. Is (20, 10) feasible?
9$20 per unit of A and $35 per unit of B: write the objective function.

🚀 Section C · Challenge ● CHALLENGE 5

10Labour ≤ 80 h; A takes 4 h, B takes 8 h. Write the constraint.
💭 Reflection — the most useful thing I learned:
