a) Draw the initial demand and supply curves based on the values given in the table above.
b) Suppose the quantity demanded rises by 20 million pounds of coffee per month at each price. On a single graph draw the initial demand and supply curves based on the values given in the table above and draw the new demand curve given by this change.
c) Suppose the quantity demanded falls, relative to the values given in the above table, by 20 million pounds per month at prices between $3 and $6 per pound; at prices between $7 and $9 per pound, the quantity demanded becomes zero. On a single graph draw the initial demand and supply curves based on the values given in the table above and draw the new demand curve given by this change.
d) Suppose the quantity supplied rises by 20 million pounds per month at each price, while the quantities demanded retain the values shown in the table above. On a single graph draw the initial demand and supply curves based on the values given in the table above and draw the new supply curve given by this change.
e) Suppose the quantity supplied falls, relative to the values given in the table above, by 20 million pounds per month at prices above $5; at a price of $5 or less per pound, the quantity supplied becomes zero. On a single graph draw the initial demand and supply curves based on the values given in the table above and draw the new supply curve given by this change.

a) Three new nightclubs open. They offer decent bands and have no cover charge, but make their money by selling food and drink. As a result, demand for movie tickets falls by six units at every price.
b) The city eliminates a tax that it had been placing on all local entertainment businesses. The result is that the quantity supplied of movies at any given price increases by 10%.
