D(x) is the price, in dollars per unit, that consumers are willing to pay for x units of an item, and S(x) is the price, in dollars per unit, that producers are willing to accept for x units. Find (a) the equilibrium point, (b) the consumer surplus at the equilibrium point, and (c) the producer surplus at the equilibrium point. D(x) = 4 -x, for 0 sx 5 4; S(x)=1/x+2 (a) What are the coordinates of the equilibrium point? Wil (Type an ordered pair.)
