What is the equilibrium price?

From Wikipedia:

Adjust Supply and Demand Equations

Demand Curve:

Qd = Pmax - D(P)

Quantity Demanded = (Maximum price a consumer will ever pay for a product) - (Rate at which demand drops as price increases) * (Price Charged per Item)

Qd =
+
(P)

Supply Curve:

Qs = Pmin + D(P)

Quantity Supplied = (Minimum Price to Sell the Product at a Profit) + (Rate at which supplier can meet increase in demand) * (Price Charged per Item)

Qs =
(P) +
