The supply function and demand function for the sale of a certain type of DVD player are given by S(p) = 140e ^{0.004 p} and D(p) = 448e ^{-0.002 p} ,whereS(p) is the number of DVD players that the company is willing to sell at price p andD(p) is the quantity that the public is willing to buy at price p. Find p such that D(p) = S(p). This is called the equilibrium price.

The equilibrium price is about $????

(Do not round until the final answer. Then round to two decimal places asneeded.)
