Respuesta :
We know that
equilibrium point is a point where demand curve and supply curve (S) intersect each other
so, D=S
so, equilibrium point is at x=40
and price at that point is p=45
we know that
revenue = price*quantity
revenue = 40*45
[tex]R=40*45[/tex]
[tex]R=1800[/tex]
so, the store will make $1800 by selling ceiling fans...........Answer
