Linear Programming & Limiting Factors

I cannot answer your question because you have not typed the whole of the question. I assume that this is a Section B type question, in which case you need the original information in the scenario to be able to answer it. (For example, earlier in the question it must have told you what the contribution per unit is. Also it must have told you what the maximum demands were. Both of these remain the same for all parts of the question). As I explain in my lectures, you cannot be asked to draw a graph in the exam, and (assuming this question came from the current edition of a Revision Kit) the question cannot be expecting you to draw one (I assume that one is not drawn in the answer in the book).
