Calculate the contribution earned from each cue

If you want me to answer then you should ask in the Ask the Tutor Forum – this forum is for students to help each other.

However, I have no idea which question you are referring to when you ask about the contribution for ‘each cue’ !!! I am guessing it is a linear programming question, but you do not say so.

Contribution is selling price less variable costs.

If it is linear programming, then have you watched my free lectures on it? The lectures are a complete free course for Paper PM and cover everything needed to be able to pass the exam well.
