Identify independent and dependent variables

Full solution

Q. Kiera baked a pan of brownies for a potluck. The number of squares she cuts the brownies into will depend on the number of people attending the potluck.

\newline

s =

the number of squares Kiera cuts the brownies into

\newline

p =

the number of people attending the potluck

\newline

Which of the variables is independent and which is dependent?

\newline

Choices:

\newline

(A)

p

is the independent variable and

s

is the dependent variable

\newline

(B)

s

is the independent variable and

p

is the dependent variable

Understand Relationship: Understand the relationship between the two variables. The number of squares Kiera cuts the brownies into $s$ is determined by the number of people attending the potluck $p$ . This means that the number of squares depends on the number of people.
Identify Independent Variable: Identify the independent variable. The independent variable is the one that is not affected by the other variable. In this case, the number of people attending the potluck $p$ does not depend on how many squares the brownies are cut into. Therefore, $p$ is the independent variable.
Identify Dependent Variable: Identify the dependent variable. The dependent variable is the one that is affected by the independent variable. Since the number of squares $s$ is determined by the number of people attending $p$ , $s$ is the dependent variable.
Choose Correct Answer: Choose the correct answer choice based on the identification of independent and dependent variables. Since $p$ is the independent variable and $s$ is the dependent variable, the correct choice is (A) $p$ is the independent variable and $s$ is the dependent variable.
