So for this question, this is a purely competitive market.
00:08
So for monopolies, marginal revenue is equal to marginal cost.
00:14
If it's purely competitive, market price is equal to market or marginal revenue is equal to marginal cost.
00:27
And if marginal revenue is not equal to marginal cost, the marginal cost should be less than marginal revenue.
00:38
For a, market price is given.
00:45
So the market price for a is 56.
00:50
So if our market price is 56, that is our marginal revenue and the marginal cost close to this on the chart is going to be 55.
01:13
How many units corresponds to 55? the quantity is going to be 8 units.
01:26
For b, market price is given as 41.
01:32
So then market marginal cost has to be less than marginal revenue.
01:39
So the closest marginal cost on the chart is 40.
01:46
Then our quantity is going to be 6 units...
