Astore’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

so, the store will make $1800 by selling ceiling fans...........Answer
