Hello!
Independent variables are variables that stand on its own, and it does not consider any other variables, also known as the domain (x-values). On the other hand, dependent variables are variables that depend on another variable, which is known as the range (y-values).
In that case, the independent variable is the hours worked, and the dependent variable is the weekly pay. Why? For how many hours she works, she gets a specific amount of pay, so hence, the weekly pay is the dependent variable.
Since "hours worked" is the independent variables, or the domain, she wants to work between 30 and 35 hours per week, so the domain is 30 to 35 hours.
To find the range, we need to create an equation. Since she gets 12 dollars per hour, the equation is y = 12x. With that, we can substitute the domain into the equation.
y = 12(30)
y = 360
y = 12(35)
y = 420
Therefore, the range is $360 to $420.
Therefore, the answer is C. hours worked; weekly pay; 30 to 35 hours; $360 to $420.
