Suppose that the quantity supplied S and quantity demanded D of T-shirts at a concert are given by the following functions where p is the price S(p)=-340+40p D(p) = 1100-50p Answer parts (a) through (c). (a) Find the equilibrium price for the T-shirts at this concert. The equilibrium price is $ 16 (Round to the nearest dollar as needed.) What is the equilibrium quantity? The equilibrium quantity is 300 T-shirts. (Type a whole number.) (b) Determine the prices for which quantity demanded is greater than quantity supplied. For the price $ the quantity demanded is greater than quantity supplied.
