Let's go over this question.
00:09
So we have our average total cost curve, average variable cost curve, our marginal cost curve which intersects the minimum of both, and then we have our line representing our price.
00:25
So our price is equal to marginal revenue and it is greater than minimum average variable cost.
00:37
So here the shutdown point is where marginal cost intersects with average variable cost or the minimum average cost point.
00:52
So if the price is still above this point the firm will still produce but we're going to have a loss.
00:57
So the quantity that it's going to produce is where marginal cost is equal to marginal revenue.
01:05
So we can estimate the quantity as 4.
01:08
So at this quantity this is where we are going to produce.
01:22
So we're going to draw the line up to average total cost and then we can calculate the area of this rectangle as the loss.
01:34
So at the quantity of 4 our average total cost is 148 and then our price is 80.
01:50
So now we can calculate the area to give us the loss.
01:55
So the base is 4 and then the height is 148 minus 80...
