Step-by-step explanation:
Independent Variable
The independent variable is the condition that you change in an experiment. It is the variable you control. It is called independent because its value does not depend on and is not affected by the state of any other variable in the experiment. Sometimes you may hear this variable called the "controlled variable" because it is the one that is changed. Do not confuse it with a "control variable," which is a variable that is purposely held constant so that it can't affect the outcome of the experiment.
Dependent Variable
The dependent variable is the condition that you measure in an experiment. You are assessing how it responds to a change in the independent variable, so you can think of it as depending on the independent variable. Sometimes the dependent variable is called the "responding variable."
To find this answer, you must first find out how much each car makes them. You do 144 divided by 24 to do this. You get the answer 6. Which means that they make $6 for each car washed.
Now that you know how much each car wash makes them, you multiply 6 by 30 to get how much they earned on Sunday.
6 x 30= 180.
So, they earned B.$180 on Sunday
