Solve the following LP using the graphical method (graph sheets attached). Compute the value of the objective function and decision variables at optimality, and indicate which statement best describes the solution.
Maximize Z = 12A + 18B
Subject to:
4A + 5B ? 10
A + 4B ? 12
A ? 4
B ? 1
A, B ? 0
(a) This LP has a unique optimal solution
(b) This LP has alternate optima
(c) This LP is infeasible
(d) This LP is unbounded
