A bakery makes cakes and loaves. Each cake uses 2 hours of labour and each loaf uses 1 hour. If at most 40 labour hours are available, which inequality represents this resource limit?
Correct answer: C. 2x + y ≤ 40
- A. 2x + y ≥ 40
- B. x + 2y ≤ 40
- C. 2x + y ≤ 40
- D. 2x - y ≤ 40
Explanation
If x represents cakes and y represents loaves, total labour use is 2x + y. Since available labour is at most 40 hours, the correct restriction is 2x + y ≤ 40.

About Linear Programming
Linear programming models the maximum or minimum of an objective function subject to linear constraints. Questions involve translating word conditions into inequalities, drawing the feasible region, identifying corner points and evaluating the objective function, including cases involving non-negativity restrictions and redundant constraints.
