Suppose firm 1 and firm 2 each produce the same product and face a market demand curve described by Q=5000-200P. Firm 1 has a unit cost of production c1 equal to 6 whereas firm 2 has a higher unit cost of production c2 equal to 10. Assume each has the capacity to serve the entire market and firms must charge prices in whole numbers (i.e. firms can't charge a price of $6.99, only $6, $7, etc.)

What is the Bertrand-Nash equilibrium outcome quantity for firm 1 & 2?
