Consider a duopoly market with 2 firms. Aggregate demand in this market is given by

Q = 500 – P,

where P is the price on the market. Q is total market output, i.e., Q = Q_A + Q_B, where Q_A is the output by Firm A and Q_B is the output by Firm B. For both firms, marginal cost is given by MC_i = 20, i=A,B.

Assume the firms compete
a la Cournot.

1. What are the equilibrium quantities?


2. What is the total quantity supplied on this market?
   


3. What is the equilibrium price in this market?
