what does dependent variable mean to you?

anonymous · Answer

the one that the equasion depends on

whpalmer4 · Answer

uh, no.  an independent variable is one that can be changed — think of it as the input to the machine that creates the dependent variables.  Here the inputs are $n$ and $a$, the numbers of children and adults, and the output is the total price of all the tickets.  The total price of the tickets is dependent on the number of tickets of each type, right?

just like how much you get paid working at your job depends on how many hours you work.  the number of hours worked is the independent variable, and the amount of pay is the dependent variable.
