-Suppose MCI and AT&T Can Each Charge Either 3¢ or 4¢

-Suppose MCI and AT&T can each charge either 3¢ or 4¢ a minute for a long distance call. The above table illustrates the payoffs, in millions of dollars, from each of the four possible outcomes that could occur in their duopoly setting. What must MCI's price be for AT&T to earn $500 million in profit?

A) 4¢ a minute
B) 3¢ a minute
C) 0¢ a minute
D) either 4¢ or 3¢ a minute because AT&T earns $500 million in profit either way
E) None of the above answers is correct because the payoff matrix shows that it is not possible for AT&T to earn $500 million in profit
