Marginal Cost & Average Total Cost - Fundamental Finance
If price is below the equilibrium price, there is an excess demand (quantity demanded For example, if I could have earned an "A" on my economics exam by spending my time Explain the law of supply and its relationship to marginal cost. of saying this: production costs that do not change with the quantity of output produced. When you add fixed and variable costs together, you get total cost. While the formula for marginal benefit is the change in total benefit divided by the change This relationship holds even though total benefits and total costs BOTH If we graph the marginal costs and marginal benefits, we will get our typical.
The total costs, obviously, are just the sum of my fixed costs and my variable costs. Let's calculate using, and I'm just using Excel, here. Let's calculate the average fixed cost, so we don't want to divide by zero. Remember, the average cost, the average fixed and the average variable and the average total cost, these are each of those costs divided by the total amount of juice that I'm producing.
You can kind of view them as the cost per gallon. So that we're thinking of the average fixed cost per gallon, so what we're going to do, so I'm writing equal to let Excel know that I'm doing a formula now, this is going to be equal to my fixed cost divided by, so divided by, divided by my gallons, and you can see that's G8 divided by F8, and actually, I guess you can't see my Gs and Fs, but this is the 8th row.
Marginal Cost Formula
If I want my average variable costs, that's going to be my variable costs divided by, divided by my total number of gallons, so that's 50 cents, so that's the first 1, gallons to produce the orange juice, the orange juice for That includes the transportation cost. Then the total is just the sum of these two things. Or, we could have done it another way.
We could have taken this right We could have said that this is just equal to, this is just equal to our total cost, our total cost divided by the total number of gallons.
Marginal Cost Formula - Definition, Examples, Calculate Marginal Cost
Either way, you'll get the same thing, and maybe I'll do a video mathematically on why that is, or maybe you should explore that yourself. Now, the marginal cost. This is equal to our change in cost, our change in total cost divided by our change in gallons of juice. Our change in total costs is going to be 1, minus 1, That's our change in total cost divided by our change in gallons, divided by 1, minus 0, our change in gallons, and that give us 50 cents.

Now, this is the fun thing about spreadsheets, one of the many fun things of spreadsheets, is now I can select all of these and fill in all of the things below it. They will use the same relative calculations. I'm going to fill without formatting.
Now, what was neat here, and I already set up this chart ahead of time, is to plot these things right over here, and so we see what's going on. This is a plot that we looked at in the last video, when we thought about software developers. This was our fixed cost, our variable costs go up as we produce more and more. What we've done here is we've plotted all of this stuff. The average fixed costs, or actually the marginal costs, the average variable costs and the average total costs.
I haven't plotted the average fixed cost here, but it's really just the difference between the total and the variable costs. Now, let's think about what's happening. First, let's look at the average, the marginal. Actually, let's look at the marginal costs first, because this is interesting, and this kind of goes in with this narrative of at first, those first oranges that we bought were expensive.
Buyers cannot purchase all of the good they would like. Some buyers will offer to purchase the good at a higher price. As price rises, quantity demanded falls and quantity supplied increases.
Thus, if price is below equilibrium, excess demand will result in an increase is price.
Marginal cost and average total cost
As price moves toward equilibrium, buyers and sellers change their actions and the quantity exchanged adjusts to the equilibrium quantity. What is marginal benefit and how does it relate to the law of demand? Marginal benefit is the benefit a consumer receives by consuming an additional unit of a good or service.
The price the consumer is willing to pay for this additional unit measures the marginal benefit he or she derives from its consumption. Generally, marginal benefit falls as an individual consumes successive units of a good.
Because marginal benefit falls as successive units are consumed, the individual will be willing to pay less for each successive unit. Thus, the law of demand, which states that there is an inverse relation between price and quantity demanded, is based upon the idea of diminishing marginal benefit.
Explain the difference between an explicit and an implicit cost. An explicit cost is a direct money outlay. An implicit cost does not involve a money outlay, but instead is concerned with the nonmonetary cost associated with an action.
For example, if I could have earned an "A" on my economics exam by spending my time studying instead of watching the movie, the "A"I sacrifice is the implicit cost of attending the movie. Will Kate plan to increase production? Why or why not?
