7. Suppose the quantity demanded falls, relative to the values given in
the above table, by 20 million pounds per month at prices between $4
and $6 per pound; at prices between $7 and $9 per pound, the
quantity demanded becomes zero. Draw the new demand curve and
show the new equilibrium price and quantity.
8. 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. Draw the new supply curve and show the new
equilibrium price and quantity.
9. 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.
Draw the new supply curve and show the new equilibrium price and
quantity.
