5. Suppose Grandis and Immanis are the only two companies that sell the product whose market demand curve is shown in the figure below. For both companies, both average total cost and marginal cost are constant and equal to $2 (ATC = MC = $2).

Suppose Grandis and Immanis agree to collude by both charging the price a monopolist would charge and each producing half of the monopolist's profit-maximizing level of output. However, Grandis decides to cheat on the collusive agreement. If Grandis charges $1 less than the monopoly price while Immanis continues to charge the monopoly price, then how many profits will Grandis will earn per day? (10%)
