Question

the johnson dairy farm produces milk and other dairy products. the number of cows on the farm changes from month to month. the amount of milk the farm is able to produce in a month depends on the number of cows on the farm.
$m$ = the amount of milk produced by the farm in a month
$c$ = the number of cows on the farm
which of the variables is independent and which is dependent?
$c$ is the independent variable and $m$ is the dependent variable
$m$ is the independent variable and $c$ is the dependent variable

Explanation:

An independent variable is the factor that is controlled or changes on its own, while a dependent variable relies on the independent variable. Here, the amount of milk produced ($m$) depends on the number of cows ($c$), so $c$ is independent and $m$ is dependent.

Answer:

c is the independent variable and m is the dependent variable
