Quizplus · Accepted Answer

The independent variable is the one that is being manipulated or changed in the equation. In this case, it is X (which represents machine hours). TC (total cost) is dependent on the value of X, so it is not the independent variable. $2,200 and $3 are constants in the equation and do not represent a variable that can be changed. Therefore, the correct answer is D) X.
