I have been practising Question 13, 14 from BPP Kit a Pass Paper June 08 Linear Programming.
I know the Constraints I know the Objective Function I Plot the Graph and have been able to determine the Feasible Region But for the life of me I am just not getting the Mix of Products that will Optimise the Profitability .
The optimal mix is at the corner of the feasible region that is farthest away from the origin when you move out the objective line (keeping it parallel).
When you have found the best corner you are expected to find the values of the two variables by solving the simultaneous equations.
