By using the definition and discussing what is relevant to the situation, interpret each of the following for both the coffee and tea data. Also, compare each for coffee and tea. Be sure to include the relevant information (state the value of or, in the case of the distribution, include the graphs) with each component.

How to determine all the basic solutions of an optimization problem, and classify them as feasible or infeasible?
As an example,
Maximize z= 2x1 + 3x2
Subject to:
x1 + 3x2 <= 6
3x1 + 2x2 <= 6
x1 + x2 >= 0
Some solutions are (2,0), (0,2), (0,0), (6/7, 12/7), but are there more solutions? And how do you tell if they are infeasile/feasible? Would you need to graph it?
