Step-by-step explanation:

OUR EQUATION IS A QUADRATIC EQUATION

Let Δ be our dicriminant :

  • a= 1
  • b= 5
  • c= -4
  • Δ= 5²-4*1*(-4) =25 +16 =41≥0

\text{State Income Tax Rate: }6.65\%, \\\text{Deduction: }\$7,702.03

Answer:

State income tax: 6.65\%

Step-by-step explanation:

Based on the interface, it seems like you have chosen lawyer as a career with the given salary of $115,820.

The chart given for state income tax is broken into two categories:

$21,400-$80,650 => 6.45%

$80,651-$215,400 => 6.65%

Since the chosen career's salary is $115,820, the career falls into the second range of 6.65% state income tax.

The deduction is simply the amount of money taxed. For a 6.65% state income tax, the deduction can be found from:

115,820\cdot 0.0665=\boxed{\$7,702.03}
