Suppose that the U.S. domestic market demand for washing machine is

P =750−2QD. (1)

There is one domestic washing machine producer in the U.S. market with the following individual supply:

P =250+3QdS. (2)

There are two foreign washing machine producers in the U.S. market, each of which has the following individual supply:

P =100+3QfS. (3)

The price of washing machine is expressed in dollars and the quantity is expressed in the number of machine per day. Assume that 1) all producers produce identical products and 2) any producer in this market behaves as a price taker.

1. (20pts) Consider the situation in which the U.S. washing machine market is opened to the foreign producers without any trade barrier. Draw a graph of the U.S. washing machine market, label the axes and the curves, and mark in the equilibrium price and quantity. Calculate the market equilibrium price and quantity.
2. (20pts) Calculate the consumer surplus, the producer surplus, and the total surplus.
