Suggest the linear optimization model Maximize 3A + 4B subject to -A + 2B ? 8 A + 2B ? 12 2A + B ? 16 A, B ? 0
a) Graph the constraints and identify the feasible region.
b) Draw the line representing all combinations of A and B that make the objective function equal to 12. c) Determine the optimal values of A and B and the optimal value of the objective function.
