In order to earn extra money over the summer, Bridgette is working as an English tutor. The amount of money she earns depends on the number of students she tutors.
m = the amount of money Bridgette earns
s = the number of students Bridgette tutors
Which of the variables is independent and which is dependent?
s is the independent variable and m is the dependent variable
m is the independent variable and s is the dependent variable
In this scenario, s is the independent variable and m is the dependent variable.
This is because the number of students Bridgette tutors (s) determines how much money she earns (m). In other words, Bridgette can choose how many students to tutor, which directly affects her earnings. Therefore, the independent variable is the one that is changed or controlled to test its effects on the dependent variable.
