Linear Programming – Q21 LD Co in BPP Kit.
Dear Sir John,
I have a question to How to construct an iso-contribution line?
Particularly if we know that: C=1.9L +6.7D
Why they have ?? If C = (1.9*6.7*1000)=12,730,
then: if L=6,700, D=0
if D=1,900, L=0.
My question , why they multiplied all thefigure in the brackets? and not added such they were supposed following the previous formule of contribution? And how they pick number 1,000?
Thank you for your answer.
Regards Jana.

10y ago#1You can pick any level of contribution you like because it is the angle of the line that is needed, and the angle will be the same whichever value you choose for the contribution.
If you watch my free lecture on linear programming then I do explain how I decide what value of contribution to choose.
Thanks John, I will watch it.
