Let's go over this question.
00:03
This is for a monopolistically competitive firm.
00:09
What is the firm's profit maximizing output level? so profit is maximized when marginal revenue is equal to marginal cost.
00:33
So we're going to find where these two curves cross.
00:42
So we have marginal revenue sloping downward and we have marginal cost, which looks like this.
00:56
So they're going to produce this quantity to maximize profits.
01:01
So that's going to be our output level.
01:16
So now if we go to the graph and we look on the horizontal axis, it looks like the profit maximizing quantity is 14.
01:42
So now what price will the firm charge? so the price they're going to charge is the point on the demand curve at the quantity that we just determined.
01:53
So we're going to draw a line up to the demand curve and then we're going to determine what price that is.
02:05
So at a quantity of 12, it looks like we end up getting 24 as the price.
02:30
At the profit maximizing price and quantity, profit is...
02:54
So our profit in the short run is going to be the price that we calculated minus the average total cost at that quantity times the quantity that we calculated in a.
03:15
So at this quantity, there's an average total cost...
