Suppose the demand for guitars in state college is given by Qd=8,000-10p where Qd is the quantity dmeanded, and P is the price of quitars. Also, suppose the supply of guitars is given by Qs=30P-2000, where Qs is the quantity supplied of guitars. find out the equilibrium price of guitars and the equilibrium quantity of guitars in State College.

Determine if there is a shortage, a surplus, or if the market is in equilibrium at a price of $500. find out how much the shortage or surplus is if there is any.
