(c) Solve your linear program using the 2-phase simplex algorithm. You should use the format given in lectures. Give a mixed strategy x E A(R) that has an optimal security level for Rosemary and a mixed strategy y E A(C) that has an optimal security level for Colin.Profits for two competing firms depend on the decisions to advertise or not to advertise as follows: If neither firm advertises, each makes a weekly profit of $100. If one firm advertises while the other does not, the firm that advertises makes $120 while the firm that doesn’t advertise makes $60. If both firms advertise, each firm makes $80. (a) What is the Nash equilibrium? Is this outcome efficient, from the perspective of the two firms?
