Decision 1 Edexcel Maths A-Level January 2013 Q2

[raving]

Do we have to show all this working? Can we not simply calculate the pivot in your head by dividing the number of remaining values by 2 and selecting the middle value (if odd), or the value immediately to the right (if even)? Then state the pivot. Would this simpler approach lose marks?

Is it possible to run through some AQA questions such as writing equations for the feasible regions ect... the edexcel questions are very different to the AQA style ones.
