### Useful Trick: Finding the minimum of AC and AVC

This video explains why setting MC = AC is a valid method to find the minimum of average cost (and the same for average variable cost). This method is useful as a means of avoiding the use of calculus, but is also illustrates the power of economic logic. The example demonstrates how to use this tool in practice.
