Question

laura is making fancy headbands to sell at a craft fair. the number of headbands she can make is limited by the amount of ribbon she has on hand.
\th = the number of headbands laura can make
\tr = the amount of ribbon laura has on hand
which of the variables is independent and which is dependent?
\th is the independent variable and r is the dependent variable
\tr is the independent variable and h is the dependent variable

Explanation:

An independent variable is the one that is changed or controlled in a scientific experiment to test the effects on the dependent variable. Here, the amount of ribbon \(r\) (the independent variable) determines the number of headbands \(n\) (the dependent variable) Laura can make.

Answer:

\(r\) is the independent variable and \(n\) is the dependent variable.
