In order to sell the remaining boxes, he needed to reduce the price to the normal price. Demand as a function of price: x = f (p) E(p) = 1 unit elasticity (demand change equal to price change) [259] If MR=MC=ATC=P then it is efficient. Both marginal revenue and average revenue tend to be downward sloping with marginal revenue often being the more steeper of the two lines. The formula for calculating the marginal revenue is as follows. When marginal revenue is higher than a firm's marginal cost, then it is making money. Sal explained this in the previous video: 'Marginal cost and average total cost' at. Why is MC = ATC the same point for both the breakeven point and an investor maximizing return?

Direct link to Stefan van der Waal's post I disagree with the claim, Let's continue with our orange juice producing example In this situation I want to think about what a rational quantity of orange juice might be what would be a rational quantity of orange juice to produce given a market price So let's say that the market price right now is 50 cents a gallon and I'm going to assume that there are many producers here so we're going to have to be price takers and obviously we want to charge as much as we can per gallon but if we charge even a penny over 50 cents a gallon then people are going to buy all of their orange juice from other people so this is the price that we can charge 50 cents per gallon So, if we think about it in terms of marginal revenue per incremental gallon well that first incremental gallon we're going to get 50 cents the next incremental gallon we're going to get 50 cents for that one and the next one we're going to get 50 cents as well. The revenue function is expressed as. To log in and use all the features of Khan Academy, please enable JavaScript in your browser.
