Question :
Suppose that the national demand and price for a certain type of energy-efficient exhaust fan are realted by p=d(q)=480-7/2q, where p isthe price ( in dollars) and q is the demand ( in thousands).
If the demand is for 68000 exhaust fans, then the price equals $____.
At a price of $ 186, the demand is for ___ thousand fans.

Suppose the price and supply of the exhaust fans are related by p= S(q)= 5/2q.
Where p is the price( in dollars) and q is the supply( in thousands) of ehaust fans.
At a price of $ 80 , the supply is ____ thousand exhaust fans .

The graphs show p= 480-7/2q w/ the graph of p= 5/2q

The equilibrium quantity is ___ thousand fans.

The equilibrium price is $ ____.
