How do you write an equation for a total cost?

Back

To write an equation for total cost, identify fixed costs and variable costs, then combine them. For example, total cost = fixed cost + (variable cost per unit * number of units).

Front

What is a variable in an equation?

Back

A variable is a symbol, often a letter, that represents an unknown value in an equation.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, perform inverse operations to both sides of the equation until the variable is alone on one side.
