Answer:
A. p is the independent variable, and s is the dependent variable.
Explanation:
In this scenario, the number of people attending the potluck is the independent variable because it is the variable that is being controlled or determined before the brownies are cut. The number of squares the brownies are cut into, on the other hand, depends on the number of people attending the potluck. Therefore, the number of squares is the dependent variable in this scenario.
