Part A
What is the 2010 federal income tax for a single person whose taxable income that year was 4000 dollars?
The function is
T(x)=0.1x
so
For x=4,000
substitute
T(x)=0.1*(4,000)
<h2>T(x)=$400</h2>
Part B
What is the 2010 federal income tax for a single person whose taxable income that year was 170000 dollars?
the function is
T(x)=0.28x-6,290.75
For x=170,000
substitute
T(x)=0.28*(170,000)-6,290.75
<h2>T(x)=$41,309.25</h2>
Part C
What is the taxable income for a single person whose 2010 federal income tax was 105000 dollars?
The function is
T(x)=0.28x-6,290.75
For T(x)=105,000
substitute
105,000=0.28x-6,290.75
solve for x
0.28x=105,000+6,290.75
0.28x=111,290.75
<h2>x=$397,466.96</h2><h2 />
119° is the correct answer.

Answer: D: $5272.
Step-by-step explanation:
Considering that all of the information is given to you already, the only thing that you need to do is plugin 9 for n.
So the final equation will look like this: 
The answer comes out to $5272.46721451 but rounding that to the nearest dollar would be answer choice D: $5272.
Equations:
Y=-50x+14,040
Y=20x+12,500
Solution X=22, Y=12,950
They will be at the same spot when the graphs intersect and the poi is (22 , 12,940)
So they will meet up at 22, 12,940
Multply across the fraction so
1/2 * 3/4= (1*3)/(2*4)=3\8
