|
$0.68

a. Is there a shortage or a surplus when the price is $0.67? What about $0.63?
b. What are the equilibrium price and the equilibrium quantity?
c. Graph the supply curve and the demand curve.
d. Show the equilibrium price and quantity on the graph.
e. If there is a shortage or surplus at a price of $0.68 calculate its size in billions of pounds and show it on the graph.
