Mr. Clifford's 60 second explanation of how to use the profit maximizing rule (MR = MC). Assume the firm is perfectly competitive and that the price is $20. Try pausing the video and identifying how much the firm should make and the profit they will make. Please keep in mind that these clips are not designed to teach you the key concepts. These videos are a review tool to help you better understand what you learned in class.
