1. Consider the perfectly competitive market for guitar tuners. The mar-ket price for a guitar tuner is $20 and the cost functions are:TC (q) = .01q² + .2q + 4950%3DMC (q) = .02g +.2(a) Find the profit-maximizing quantity of guitar tuners produced bya firm in this market.(b) Calculate the profit each firm will earn in this market(c) Graphically depict the firm's profit-maximization problem. (note:this doesn't need to be to scale but should accurately reflect the signof the profit)(d) Will firms enter into this market in the long run?(e) Graphically show how the price will change as the market pro-gresses towards a long-run equilibrium. (There's no need to findthe exact long-run equilibrium price. Just follow similar steps towhat we did in class)

Since you have posted multiple parts question, we will solve the first three parts for you. If you…

Suppose that each firm in a competitive industry has the following identical costs: Total cost: TC = 25+0.25Q2,where Q is an individual firm’s quantity produced. The market demand curve for this product is as follow: Demand: P=60-0.095Q,where P is the price and Q is the total quantity of the good. Currently. (i) Identify each firm’s fixed cost, variable cost, and its marginal cost. (ii) Suppose that there are 10 firms in the market. Construct the market supply function in the short run. Determine the equilibrium price and quantity. (Hint: If each firm’s supply function is Qi= a+bP then the market supply Qm can be the aggregated supply at each price as Qm = Q1+Q2+Q3+...+Qi where Qi is each firm’s supply function.) (iii) Calculate each firm’s production quantity and profit (or loss) in the short run. Predict whether a firm will decide to leave or stay in the market as well as the long-run market equilibrium with free entry and exit.
