Let the demand and supply functions be represented by p=D(q) and p=S(q), respectively, where p is the price per item in dollars and q is the quantity of items. D(q) = 42.03q S(q) = .02q 20
Find the equilibrium price. Hint: you will first find the equilibrium quantity (q) and once you know this you can find the equilibrium price (p)

At equilibrium supply equals demand
42.03q=.02q20
.01q=20
q=2000
