In a perfectly competitive industry, each firm has a total cost
function of TC = 400 + 10q + q2 and a marginal cost curve of MC =
10 + 2q if it produces a positive quantity of output q. If a firm
produces zero output it has no costs. The market price is $50.
Which statement is true?]
a. Each firm produces 20 units of output; the industry will
require entry to reach its long-run equilibrium.
b. Each firm...
Suppose in the short run a perfectly competitive firm has the
total cost function: TC(Q)=675 + 3q2 where q is the firm's quantity
of output. If the market price is P=240, how much profit will this
firm earn if it maximizes its profit?
b) how much profit will this firm make?
c) Given your answer to b), what will happen to the market price
as we move from the short run
to the long run?
d) What is the break-even...
Q1. Assume a perfectly competitive firm's total cost (TC) for
differents levels of oututes Q is given by:
Q TC
0 50
1 100
2 140
3 170
4 190
5 210
6 230
7 260
8 300
9 350
10 410
In the table format for the range of output (Q) provided
determine: average total costs, average fixed cost, average
variable costs, and marginal costs. At a price of $35 how many
units will be produced in the short...
A firm produces a product in a competitive industry and has a
total cost function TC = 50 + 4Q +2Q² and MC = 4 + 4Q. At the given
market price of $20, the firm is producing 5 units of output. Is
the firm maximizing profit ? What quantity of output should the
firm produce in the long run?
A firm operating in a perfectly competitive market has the
following total cost function: TC=0.4Q2+40 There are 20
identical firms in the short-run in the market. In addition, the
demand function is given by: Q=300-5P
a) Find the Supply Function for the Firm in the
short-run

quantity in the market in the
short-run?
c) How much does each of the 20 firms produce in the
short-run?
d) How much profits does each firm...
A firm in a perfectly competitive market has the following cost
curve: TC = 200 + Q + 2Q^2 and The market demand is: Qd = 121 - P.
There are 20 identical firms in the market (N =20) in the
short-run.
e) At the equilibrium price found in part (c), how much profit
is each firm making in the short-run? Will there be entry or exit
in this market in the long-run?
f) What is the price of the...
A firm in a perfectly competitive market has the following cost

Say the firm is a perfect competitor. If the market price for
its product is $ 60, at what output level will this firm produce at
(as a profit maximizer)?
At the output level in (a), are firms in this industry making a...

An industry is perfectly competitive. Each firm is identical and
has a total cost function T C(q) = 50 + 2q^2 . The market demand
function for products is Q = 1,020 − P, where P is the market
price.
