Question

edna is making frosting for some cupcakes she baked earlier. the amount of frosting needed depends on how many cupcakes there are.
f = the amount of frosting needed
c = the number of cupcakes
which of the variables is independent and which is dependent?
c is the independent variable and f is the dependent variable
f is the independent variable and c is the dependent variable

Explanation:

An independent variable is the one that is changed or controlled in a situation, and the dependent variable depends on the independent variable. Here, the number of cupcakes (\(c\)) determines the amount of frosting needed (\(f\)), so \(c\) is independent (it can be chosen freely, like baking a certain number of cupcakes), and \(f\) is dependent (it depends on how many cupcakes there are).

Answer:

c is the independent variable and f is the dependent variable
