Question

The drama club is having a bake sale selling cupcakes to raise money. They spend $32 on supplies and sell each cupcake for $5.

Let n represent the number of cupcakes they sell and m represent the money earned.

Which variable is the independent variable and which variable is the dependent variable?

Answer 1

n (number of cupcakes) is the independent variable and m (money earned) is the dependent variable.

Reason: the money earned depends on how many cupcakes are sold. (You can express this as m = 5n − 32.)
