Lasguns are produced by identical firms in a perfectly competitive market. Each firm's Total Cost function is TC=404+q^2 and Marginal Cost function is MC=2q. Market demand is Q=621-P. How many firms are in the market in the long-run?

A firm operates two plants.  The total cost schedules for the respective plants are TC1 = 5*Q1 + .1*Q12 and TC2= 2*Q2 + .1*Q22.  The firm’s demand schedule is Q = 160 – 10*P. What is the profit maximizing output for the firm?

Glowglobes are produced by identical firms in a perfectly competitivemarket. There are 22 firms in the market. Each firm's Total Cost functionis TC=473+2q+q^2 and Marginal Cost function is MC=2+2q. Marketdemand is Q=485-P. What is the quantity produced by each firm in the short-run?

Can these be answered as well?  Derive the firm's average cost and average variable cost curves.  What q should the firm choose so as to maximize its profit if the market price is p?

Consider the market for ice cream. Suppose that this market is perfectly competitive. The cost structure of the typical ice cream producer is as follows. Average total cost is equal to 50 ATC(Q) = +;Q, average variable cost is equal to AVC(Q) Q, and marginal cost is equal to MC(Q) = Q. How many ice cream cones will each producer sell in a long-run equilibrium in the market for ice cream?

Lasguns are produced by identical firms in a perfectly competitive market. Each firm's Total Cost function is TC=470+13q+q^2 and Marginal Cost function is MC=13+2q. Market demand is P=401-2Q.  What is the long-run equilibrium market price?

Glowglobes are produced by identical firms in a perfectly competitive market. There are 19 firms in the market. Each firm's Total Cost function is TC=396+2q+q^2 and Marginal Cost function is MC=2+2q. Market demand is Q=484-P.  What is the profit earned by each firm in the short-run?

I need solution of a,b,c

A firm sells its product in a perfectly competitive market. Its total cost function is: TC = 900 - 20Q + Q2where TC is total cost and Q is output level.a. Find the firm’s average total cost function. b. Find the firm’s average variable cost function. c. Find the firm’s marginal cost function. d. Given the price is $100, what is the profit-maximizing output level? e. Given the price is $100, what is the profit level? f. Over time, is there going to be entry or exit in this competitive market? Why?

The market for drones is perfectly competitive. Assume for simplicity that fractions of everything, including firms, is possible. We have identical firms, each with a Total Cost curve of TC=376+91q+q^2 and Marginal Cost curve MC=[b]+2q. Market demand is Q=695-2P. What is the Average Total Cost if the firm produces 37 units?
