So we're given a cost function with the following graph.
00:03
The associated marginal cost, well, it depends because marginal cost is equal to the derivative of the cost.
00:18
So in this case, we see that even though the graph is changing, it does have a fairly standard slope.
00:28
If we just consider a line that goes from this point to the end point, going through the whole thing.
00:35
So this is just what the marginal cost is approximately.
00:40
So in this case, we just consider the fact that you have the point about 0 ,500 is the first point.
00:48
And then the last point is about maybe 175 ,000.
01:00
Just an estimate.
01:02
If you actually have the graph in front of you, it might be a little easier...
