"Marginal Revenue and the Demand Curve." (the demand function) of price; the inverse demand function treats price as a function of quantity demanded, and is also called the price function:[2]. Now there's two dynamics here we want to produce as much as possible so that we can spread our fixed cost over those gallons that's one way of thinking about it or, another way of thinking about it is we have a certain amount of fixed cost we are spending $1000 no matter what so why don't we try to get as much revenue as possible to try to make up for those fixed costs or if we think about it in terms of average fixed cost the more quantity that we produce the component of the cost for that from the fixed cost goes down and down and down so we want to have as much as possible to spread our fixed costs now the one thing that we do need to think about is especially once we kind of get beyond the little dip in the marginal cost curve and as we produce more and more units the marginal cost is going up higher and higher and higher we don't want to produce so much that the cost of producing that incremental unit the marginal cost of that incremental unit is more than the marginal cost of that actual or the marginal cost of that incremental unit is not higher than the marginal revenue that we're getting on that incremental unit so, until marginal revenue is equal to marginal cost or another way to think about it you don't want marginal cost and this is after we go to this little dip here we're trying to do as much as possible marginal cost is going higher and higher and higher we don't want to produce this much right over here because here the cost for that extra gallon is higher than what we're going to get for that extra gallon looks like that cost for that extra gallon might be 53 cents while we're only gonna get 50 cents for that extra gallon so every extra gallon we produce over here we're going to be losing money so you don't want marginal cost to be greater than marginal revenue so when you look at the curves like this and make sense to just say when does marginal revenue equal marginal cost?
