Suppose the demand and supply curves of salt are given by: qD = 1,000 - p qS = 700 + 2p (a) Find the equilibrium price and quantity. (b) Now, suppose that the price of an input that used to produce salt has increased so, that the new supply curve is q$ = 400 +2p How does the equilibrium price and quantity change? Does the change conform to your expectation? (c) Suppose the government has imposed a tax of Rs 3 per unit of sale on salt. How does it affect the equilibrium rice quantity
