It is given that inverse demand curve p is equal to 50 minus 0 .4 q mc is equal to 10 is equal to atc mc is marginal cost and atc's average total cost in question a we have to find profit maximization price for seller.
00:57
We know that profit is maximized when marginal cost equal to marginal revenue.
01:22
Here total revenue, total revenue, pr equal to p into q.
01:33
We know that total revenue equal to p into q.
01:36
So, putting the value of p, which is 50 minus 0 .4 q into q, we will get total revenue.
01:54
So solving this, we will get 50 q minus 0 .4 square.
02:07
Now, we will find mr.
02:10
That is marginal revenue.
02:12
Marginal revenue is draped by differentiating total revenue.
02:17
With respect to q.
02:19
Here, tr is 50 q minus 0 .4 square.
02:23
We will differentiate it with respect to q to find marginal revenue.
02:29
Marginal revenue equal to dtr by dq.
02:35
So d by dq, total revenue is 50 q minus 0 .4 q.
02:43
In differentiating it, we will get 50 minus 0 .0...
