-----------
Definition
Costs that do not vary with the level of output of the firm.
----------
Term
What is the Definition of Total Variable Costs?
--------
Definition

On a graph how are Total Costs and Total Variable Costs represented?
--------------------
Definition
As parallel curves
---------
Term
On a graph how are Total Fixed Costs represented?
--------------------
Definition
As a horizontal line that divides Total Costs and Total Variable Costs curves.
--------------
Term
How does one calculate Average Fixed Cost?
----------------
Definition
Total Fixed Costs Divided by Quantity Produced
-----------------
Term
How are Average Fixed Costs represented on a graph?
------------------------
Definition
A negative sloping curve
---------------
Term
What is the Definition of Average Fixed Costs?
-------------
Definition

-------------------
Term
How does one Calculate Average Variable Cost?
-------------
Definition
Total Variable Costs Divided by Quantity
-------------
Term
How are Average Variable Costs represented on a graph?
----------------
Definition
As a "U" shape that's vertex is at the Maximum Quantity of Labor.
---------------
The left half represents increasing marginal returns.
-------------
The right half represents diminishing marginal returns.
---------------
Term
How does one calculate Average Total Costs when provided with the Total Cost and Quantity?
--------------
Definition
Total Costs Divided by Quantity
-----------
Term
How does one calculate Average Total Costs when provided with Average Variable Cost and Average Fixed Costs?
----------------
Definition
Average Variable Costs plus Average Fixed Costs
--------------
Term
How does one calculate Average Fixed Costs, when provided with Average Total Cost and Average Variable Costs?
---------------------
Definition
Average Total Costs Minus Average Variable Costs
-------------------
Term
How are Average Total Costs, Average Variable Costs, and Average Fixed Costs represented on a graph?
--------------------
Definition
Average Total Costs and Average Variable Costs are positively sloping curves, while Average Fixed Costs is a negative sloping curve.
-----------------------
Term
How does one calculate Marginal Cost when provided with Change in Total Costs and Change in Quantity?
----------------
Definition
Change in Total Costs Divided by Change in Quantity
-------------
Term
How does one calculate, in a short run, Marginal Cost when provided with Change in Total Costs and Change in Quantity?
----------------
Definition
Change in Total Variable Costs Divided by Change in Quantity
---------------
Term
Do Total Fixed Costs Vary or are they constant?
----------------
Definition
They are constant
--------------
Term
How is Marginal Costs represented on a graph?
-----------------
Definition
It is a positive curve, "J" shaped, that curves upward through the Average Total Cost and Average Variable Cost curves, through their minimum points.
-------------------
Term
What do you do if a Total Cost Function is given in this form?
TC=A+BQ+(CQ^2)
----------
Where "Q" is the output
-----------
Definition
Total Fixed Costs Equals "A"
Because "A" does not vary
---------------------
Total Variable Costs Equals
BQ+(CQ^2)
Because these terms vary
---------------------------
Average Fixed Costs Equal A/Q
Because AFC=TFC/Q, TFC=A
--------------------------------
Average Variable Costs Equals
B+CQ
Because AVC= TVC/Q
----------------
Average Total Costs Equals
AFC+AVC
------------------------
