Answer:
$6 per bushel
3 thousand bushels
Explanation:
The equilibrium price is the price for which the quantities demanded and supplied are the same, regardless of the price floor.
The equilibrium quantity is given by:
[tex]P_D=P_S\\9-Q=2Q\\Q=3\ thousand\ bushels[/tex]
The equilibrium price is:
[tex]P = 9 - Q = 9-3\\P=\$6[/tex]
At market equilibrium, the price is $6 per bushel, and the equilibrium quantity is 3 thousand bushels.
