Since the solution to the system of equation is 12 and -12, hence the equation has 2 solutions
<h3>Modulus functions</h3>
Modulus functions are functions that can either be positive or negative. Given the modulus function below;
|h| − 8 = 4
The modulus of h can both be negative and positive
If the modulus of h is positive then;
h - 8 = 4
Add 8 to both sides
h-8 + 8 = 4 + 8
h = 4 + 8
h = 12
If the value of h is negative
-h - 8 = 4
-h = 4 + 8
h =-12
Since the solution to the system of equation is 12 and -12, hence the equation has 2 solutions

Answer:
Effective tax rate of Maria is 5.08%.
Step-by-step explanation:
Effective tax rate ETR = 
As a percent we can represent ETR = 
×100
In this question Maria has a total tax = $3072 and gross income = $60449
By putting these values in the formula ETR = 
×100 = 5.08
Therefore her effective tax rate is 5.08%.
