On the other hand, factors such as the house call charge or the price of an hour for labor are fixed and do not change.
Moreover, in equations, the factor that changes and can affect others is known as the independent variable. This means the number of hours can be classified as the independent variable because this is not fixed and affect other variables including the total cost.
