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)= (x-6)^2
S(x)= x^2 + 4x + 4
