given the demand function Pd=25-Q2and supply function Ps = 2Q+1. Assuming pure competition, find the consumer and producer surplus

None

Consider the market for bicycles in the fictional province of Westvale. The market demand function for bicycles is given by P=300-2Q. The marginal cost curve for firms in this market is given by P=40+Q. Prices are measured in dollars.    a) Under a competitive market equilibrium, what is the price of a bicycle?  b) How many bicycles are produced under a competitive market equilibrium?  c) Calculate consumer surplus, producer surplus, and total surplus under the competitive market equilibrium    Suppose that the firms that were once competing in this market merge into one single firm, forming a monopoly. This monopoly has a marginal revenue function of P=300-4Q. d) What price does this monopolist charge?  e) How many bicycles does the monopolist produce?  f) Calculate consumer surplus, producer surplus, and total surplus under the monopolistic market outcome  g) How much deadweight loss resulted from the creation of the monopolist?

Given a demand of q = 100 – 5p and a cost of c(q) = 4q. What is the equilibrium retail price p, wholesale price w, and profits from the manufacture and sale of the product?
