If the price is 7, how much will the firm produce? so in this case, this is perfectly competitive.
00:13
Price is equal to marginal revenue.
00:16
It's going to produce where marginal revenue is equal to marginal cost.
00:20
So, i'm going to draw a straight line at 7.
00:26
And we're going to see where it crosses with marginal cost.
00:29
So the output would be 40 units per day.
00:33
And what is the average total, average variable, and marginal cost? so average total cost at this level of output is going to be 4.
01:14
And then what we're going to do is define the total cost.
01:20
We take average total cost multiplied by the quantity.
01:24
So at the quantity of 40, average total cost is 4.
01:28
Multiply these together and we get total cost is 160.
01:35
For total variable cost, we see that at 40, average variable cost is going to be 3...
