MIRRORS. Manufacturers are only willing to sell mirrors at prices at least as high as the shutdown price. In the competitive market for mirrors, the quantity supplied for a particular market price is Q5 = 10 + EP when P > 20, as well as Q5 = 0 when P S 20. Meanwhile, the demand function is Qd = 10 - if) + :Y , which describes the quantity demanded when the market price is P and the level of income in the market is Y. a. Find the equilibrium price as a function of lncome Y. b. Income Y impacts the demand curve, but not the supply curve. For some level of income Y, there is an 5 equilibrium at which the own-price elasticity of supply is + 5. Find the equilibrium, P*, 9* 1, and this income Y. Optional soundtrack: first 40 seconds of www.youtube.com/watch?v=HG7I4oniOyA 0. Draw a welllabeled supply and demand diagram for this equilibrium, clearly showing the equilibrium values of Q" and P*. Draw both curves carefully for prices on [0, 120]
