Answer:
State income tax: 
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:

Simply take the numerator (3) and denominator (7) and add them together.
3+7 = 10, which means that the ratio will provide parts that are in multiples of 10 depending on the total
so take 10x = 800
x = 80.
Then multiply this by the numerator and denominator
3*80/7*80 = 240/560.
Answer
20
Step-by-step explanation:
-4*20=-80
-4+20=16
2. 14x+15x, or 29x (simplified form)
3. 27x+5x, or 32x (simplified form)
4. 64x+6x, or 70x (simplified form)
Hope this helps.
I dont really know if this is right myself, but i'm just using the skills my teacher thought me.
