Respuesta :

The correct answer is:

C: hours worked; weekly pay; 20 to 25 hours; $180 to $225

Explanation:

The independent quantity is the quantity that causes a change in the dependent quantity.  In this problem, our quantities are hours worked and weekly pay.  The number of hours she works causes her weekly pay to change; thus, hours worked is the independent quantity and weekly pay is the dependent quantity.

Since she plans to work between 20 and 25 hours, this means the domain is 20 to 25.  Since she is paid $9 per hour, this makes the range 9(20) = $180 to 9(25) = $225.
