1. Consider a product whose demand function is D(q) = 900 − 20q − q2 (in dollars) and whose supply function is S(q) = q2 + 10q (in dollars) for producing q items.
(a) Look at the graph of the supply and demand curves (you may do this on a graphing utility, such as a graphing calculator, Desmos.com, Wabbitemu phone app, etc).
(b) Find the equilibrium price and quantity.
(c) Find the consumers’ surplus.
(d) Find the suppliers’ surplus
