A nurse has an income of $120,000. The income tax the nurse has to pay is 6%. What is the amount of income tax, in dollars and cents, that the nurse has to pay?

7,200 I believe

Step-by-step explanation:

$7,200.00

Step-by-step explanation:

1. We assume, that the number 120000 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 120000 is 100%, so we can write it down as 120000=100%.

4. We know, that x is 6% of the output value, so we can write it down as x=6%.

5. Now we have two simple equations:

1) 120000=100%

2) x=6%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

120000/x=100%/6%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 6% of 120000

120000/x=100/6

(120000/x)*x=(100/6)*x       - we multiply both sides of the equation by x

120000=16.6666666667*x       - we divide both sides of the equation by (16.6666666667) to get x

120000/16.6666666667=x

7200=x

x=7200

now we have:

6% of 120000=$7200
