need help in part C, thankss

The supply and demand sets for a market are 3 = {(w) Ip 3q= 6} and D = {(q,p) |p+ 2q=16}. (a) Find the equilibrium price and quantity for this market. (b) The cobweb model dictates that, for t 2 1, a market will evolve according to the formulae Qt = QSUJtI) and Pr = PD(qt]- Find a recurrence equation which describes how the price changes with time if this market evolves in accordance with the cobweb model. If the initial price is tenJ solve this equation and describe how pg behaves as t increases. Also nd Q; as an explicit function of t. (c) If the government imposes a percentage [of the price] tax of 100r% on the sale of goods in this market, the price including the tax is p... and the equilibrium price is now determined by the equation qsa - m) = qD(a-l- Find the equilibrium price and quantityr for this market in the presence of this tax. For what values of 1' will this equilibrium be economically meaningful
