The demand and supply schedules for gum are given in the table. a.
Draw a graph of the gum market, label the axes and the curves, and mark in the equilibrium price and quantity. b.
Suppose that the price of gum is 70¢ a pack. Describe the situation in the gum market and explain how the price adjusts.
Suppose that the price of gum is 30¢ a pack. Describe the situation in the gum market and explain how the price adjusts. d.
A fire destroys some factories that produce gum and the quantity of gum supplied decreases by 40 million packs a week at each price. Explain what happens in the market for gum and illustrate the changes on your graph.
If at the time the fire occurs in d, there is an increase in the teenage population, which increases the quantity of gum demanded by 40 million packs a week at each price. What are the new equilibrium price and quantity of gum? Illustrate these changes in your graph.
