Which variable causes a change in the other variable?
Independent Variable: w Dependent Variable: A
Practice makes perfect
We want to identify the independent and dependent variables of the given equation.
A=25w
This equation represents the area A of a rectangular dance floor with a width of w feet. To identify which variable is independent and which is dependent, we need to analyze which variable causes a change in the other variable.
Independent Variable: Causes change in the dependent variable.
Dependent Variable: Changes because of the independent variable.
The value of the dance floor width causes the area to increase. In other words, the area A depends on width w of the dance floor. Therefore, w is the independent variable and A is the dependent variable.
