So let's go over this question.
00:08
So we have marginal revenue, marginal cost, demand, and average total cost.
00:23
So our profit maximizing point is going to be where marginal cost is equal to marginal revenue.
00:33
So our price is going to be the price on the demand curve at the equilibrium quantity.
00:42
And then we can see that this is going to be less than the average total cost at this equilibrium quantity.
00:49
So therefore there's going to be a loss.
00:55
And that's going to be indicated by this rectangle.
01:00
So then for the next part we want to get total revenue and total cost.
01:14
Total revenue is equal to price times quantity.
01:18
So the price is given by the demand curve.
01:24
So we get $2 .75 as the price at the equilibrium quantity.
01:31
Then we need the quantity which turns out to be $1 ,250.
01:50
So we're selling that much at that price giving us the total revenue.
01:54
Now we need the total cost.
02:12
That's average total cost times the quantity.
02:17
So our average total cost turns out to be $3...
