Question

Consider an oligopoly with 5 firms. The market inverse demand curve is p=230- 4Q. The firms make identical products, have no fixed costs, and face a constant marginal cost of $30 per unit produced.
Suppose the 5 firms are engaged in Bertrand competition.
What is the equilibrium price?
How much output is made in total by the 5 firms?
How much output does each firm make?
How much profit does each firm earn?
Suppose the 5 firms form a cartel with each firm producing an equal share of the output.
