We know that :

From the figure, We can notice that :
↔ Opposite side of Angle Q is 9 units
↔ Hypotenuse is 15 units


Answer:
The domain: all real numbers;
The range: 
Step-by-step explanation:
The graph of the function y=|x| opens up and has a vertex at (0,0). If the graph of an absolute value function opens up and has a vertex of (0, -3), then the function has an expression
y=|x|-3 (see attached diagram).
The domain of the parent function y=|x| is the set of all real numbers, then the domain of the function y=|x|-3 is the set of all real numbers too.
The range of the parent function y=|x| is
then the range of the function y=|x|-3 is 
Well one week she'd have 23.50$. So per week you multiply that number by the number of weeks.
I hope this is what you were looking for, the question was a bit confusing.
Yes that is correctttttttttttttttt
