c. Suppose instead that several major bicycle producers go out of business, thereby reducing the quantity supplied by 8 million bikes at every price. Find the new equilibrium price and quantity, and show it graphically. Explain again why quantity falls by less than 8 million.
d. What are the equilibrium price and quantity if the shifts described in Test Yourself Questions 3(b) and 3(c) happen at the same time
