Because (as I explain in the lecture) if we move the contribution line away from the origin while keeping it parallel, then B is the furthest away that we can get without leaving the feasibly region.
I do explain in the lecture that you can choose any contribution you want because all we need is the gradient/slope of the contribution line, and this will be the same whatever level of contribution you choose.
can you tell me why you used 2.5 to multiply and why used material instead of labour to calculate by 2.5 is it because optimum region was at the material line or because it has a 2s+4e
Bacuse you cannot know without drawing the graph which will be the limiting factors – it will not always be simply materials and labour (it depends on the angle of the contribution line).
Also, since the question will almost certainly ask for the graph then there will be marks specifically for the graph. If you do not draw it then you will obviously lose marks.
morning sir,you mentioned something like the highest point of contribution is not always where the labour and material line intersects.my question is, can any of the two constraints give the highest contribution without having the two constraints intersecting?

how do we know that maximum contribution occurs at point B?

Hi, based on what you selected 90 as contribution?

John Moffat says
It is simply to get the same number of S’s in both equations.

Dear Sir
What is the relevance in drawing graph when we can solve the problem by equating material and labour equation?

hello sir
i was wondering if linear programming is still part of the f5 syllabus.It wasnt covered in the revision notes nor the practise exam qns section.
John Moffat says
Of course it is in the syllabus, and we have several lectures on it!
Surely you have looked at the syllabus on the ACCA website?
(The revision lectures are just meant to be quick revision – it is the main lectures that should be used for learning!)
sinnie96 says
Sir ,the iso contribution line ,we want to find out the point and match within the feasible area and also less than demand line isn鈥檛 ?
John Moffat says
The only relevance of the demand line is that it is part of defining the feasible area.
sinnie96 says
ok thanks sir
John Moffat says
You are welcome 馃檪

Hi,
I wanted to clarify one thing,if we plot S on x axis and E on y axis,that wouldnt change the maximum contribution/optimal production right?
John Moffat says
No – although the lines will look different it will not (and can not) change the answer!
furqan.90 says
Thanks.
