19. My calculations are off but I'm not sure where.

D(x) is the price, in dollars per unit, that consumers are wiling 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 un19, 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+15. 5(X]=3x+3 (a) Find the equilibrium point (6.11) (Type an ordered pair, using integers or decimals ) (b) Find the consumer surplus at the equilibrium point. $ 22.30 (Type an integer or a decimal ) [c) Find the producer surplus at the equilibrium point 14.39 (Type an integer or a decimal.)
