3: The equilibrium price and quantity of the Y product is P = 15 v Q = 20. At this equilibrium, the demand elasticity is Ep = -0,5 and the supply elasticity is Es = 0,5. The demand and supply curve are linear lines a. Define the demand and supply equations of this Y market. b. Make assumption that the supply decreases 50% after the government put tax on this product. What are the changes of the equilibrium price and quantity? c. After tax, the government continues set the price ceiling P = 15. How the market supply and demand would be like?
