variable expression
The process of writing units of each variable in a real-life problem is called dimensional analysis or unit analysis. It is useful for understanding the real-life problem and for checking to see we get a valid answer. Please see the links for additional explanations.

unitanalysis
If the unit rate exists, it is the ratio of one variable relative to the other.
unitanalysis
The unit of each variable is dependent of what is being measured.
Variable cost per unit= Total Variable costs($ amount) divided by Production units
Variable cost per unit = Total variable cost / total number of units manufactured
Because variable cost per unit took an arrow to the knee.
Variable cost per unit= Total Variable costs($ amount) divided by Production units
Solve the problem using the + sign for the variable. Then solve the problem using the - sign for the variable. Report your answer as the answer that you got using + or the answer that you got using -.
