kaplan exam kit-2012, Q no. 19, page 19. in the solution on pg 126, i didnt understand where ddi the subject to constraints 80X+130Y+S1=60000 came from and can u please explain the graph ?
I only have the latest edition of the Kaplan exam kit, and either you have typed the constraint wrongly or there was a typing error in the exam kit (which is now correct).
The constraint relates to Assembly time (S1) and is 80X + 130Y <= 60,0000
(each X takes 80 minutes; each Y takes 130 minutes; the total time available for assembly is 1,000 hours, which is 60,000 minutes.With regard to the graph – which bit do you want explaining? (It is obviously impossible on here to explain every single part of the graph). If you have problems in general with drawing graphs, then best is to watch my lecture on linear programming.
