 (b).Simplex
methods:  The Simplex method is an
approach to solving linear programming models by hand using slack variables,
tableaus, and pivot variables as a means to finding the optimal solution of an
optimization problem.  A linear program
is a method of achieving the best outcome given a maximum or minimum equation
with linear constraints. 

The method produces an
optimal solution to satisfy the given constraints and produce a maximum zeta
value
