Show the equilibrium graphically. b. Suppose a $12 excise tax is imposed on the good. Determine the new equilibrium price and quantity (see video on inverse functions).The following are market demand and supply equations for a perfume product:QD = 70 − 4PQS = 10 + 2Pwhere P is, QD and QS are quantity demanded and supplied of perfume, respectively.A) What is the equilibrium price and quantity? Calculate using the arithmetic method.B) Draw demand and supply curves for prices £0, £4, £6 ... £16.C) Suppose consumers’ income increases and perfume is considered as a normal good. As a result, the new demand equation is QD = 100 − 4P. Find the new equilibrium price and quantity of perfume.
- Due to a recession that lowered incomes, the 2008 market prices for last-minute rentals of U.S. beachfront properties were lower than usual. Suppose that the inverse demand function for renting a beachfront property in Ocean City, New Jersey, during the first week of August is Derive the equilibrium price, p, and the quantity, Q", in terms of Y.
