Consumers in a certain state choose between three long distance telephone services. GTT, NCJ, and Dash. Aggressive marketing by all three companies results in a continual shift of customers among the three services. Each year, GTT loses 30% of its customers to NCJ and 20% to Dash, NCJ loses 15% of its customers to GTT and 5% to Dash, and Dash loses 5% of its customers to GTT and 30% to NCJ. Assuming that these percentages remain valid over a long period of time, what is each company's expected market share in the long run?
