Answer:
C is dependent, B is independent
Explanation:
The dependent variable is the number that is affected when you change the independent variable—it depends on the independent variable.
Does the number of cookies remaining in the jar depend on the number of cookies in the jar before your visit, or does the number of cookies in the jar before your visit depend on the number of cookies remaining in the jar.
The number of cookies remaining in the jar depends on the number of cookies in the jar before your visit. Therefore, the number of cookies remaining in the jar is the dependent variable, and the number of cookies in the jar before your visit is the independent variable.
Therefore, C is the dependant variable, and B is the independant variable.
