Question

in order to earn extra spending money, rachel babysits children after school. the greater the number of hours she babysits, the more money she earns.
\th = the number of hours rachel babysits
\tm = the amount of money rachel earns
which of the variables is independent and which is dependent?
\tm is the independent variable and h is the dependent variable
\th is the independent variable and m is the dependent variable

Explanation:

An independent variable is the one that is manipulated or chosen freely, and the dependent variable depends on the independent variable. Here, the number of hours \( h \) Rachel babysits is chosen by her (or varies independently), and the money \( m \) she earns depends on the number of hours (since more hours mean more money). So \( h \) is independent, \( m \) is dependent.

Answer:

h is the independent variable and m is the dependent variable
