A store’s supply/demand graph for ceiling fans is shown above. If the price is at the equilibrium point, how much money will the store make selling ceiling fans?

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
