1 Question 1 (15 marks)

The supply of mango in Sydney is P = 2+Q and the demand of mango is P = 8−2Q.

2. If the price of the mango is \$6, how many mangoes are supplied in the market? how many mangoes are demanded in the market? Is this an excess of supply or a shortage of supply? (3 marks)

3. Draw the Supply and demand curve and find the equilibrium. (3 marks) Calculate the consumer surplus and supplier surplus. (3 marks) Calculate the elasticity of demand at the equilibrium point. (3 marks)

4. Calculate the elasticity of demand when the price is \$2. If we ignore the supply curve, will the revenue decrease or increase when the price is \$2, comparing to the equilibrium point? (3 marks)
