Step-by-step explanation:
The root is
-sqr root of 5.

where a is the root
So we have
To get rid of that square root, let have another root that js the conjugate posive root of 5.
Which will gives us a rational coeffeicent of degree 4.
Why we didn't do
?
Because
If we foiled out we will still have a irrational coeffceint.
Simple,
Total=$82.50
Total Hours Worked= 7.5
82.50/7.5=11
Thus, your hourly rate of pay, is $11.
