ACCA PM · Chapter 6 · Question 10 of 10
Psi Co makes products X and Y. Each unit of X uses 2 kg of material M and each unit of Y uses 5 kg. Only 10,000 kg of material M are available. Each unit of X earns contribution of $12 and each unit of Y $25. If x and y are the units produced, which of the following correctly states the material constraint?

Reveal answer & explanation
Correct answer: A) 2x + 5y <= 10,000
Explanation
Each unit of X uses 2 kg and each unit of Y uses 5 kg, so total material used is 2x + 5y, which cannot exceed the 10,000 kg available. Contribution figures belong in the objective function (maximise 12x + 25y), not in the resource constraint.
