In most linear programming problems, there are two stages:
1. to interpret the information given as a series of simultaneous
inequalities and display them graphically.
2. to investigate some characteristic of the points in the unshaded
solution set.
Example
A shopkeeper buys two types of cat food for his shop: Bruno at 40c
a tin and Blaze at 60c a tin. He has $15 available and decides to buy at
least 30 tins altogether. He also decides that at least one third of the
tins should be Blaze. He buys x tins of Bruno and y tins of Blaze.
a) Write down three inequalities which correspond to the above conditions.
b) Illustrate these inequalities on a graph.
