If Arman's pay after taxes is 499.61 then you would need to subtract this from his pay in the first place to find the difference. This would be how much he paid in taxes overall.
625.00 - 499.61 = 125.39
Now we need to find out how much he paid in federal income taxes. So we subtract how much he paid in other taxes from the total amount he paid to get how much he paid in federal income tax.
125.39 - 38.45 = 86.94
Your answer is (C)

First we need to find out how much he makes at both jobs. So we add 200 dollars to 175 dollars.
200 + 175 = 375
Then we need to know how much he paid in total taxes from both jobs. So we need to add 42 dollars to 24 dollars. This is how much he paid in total taxes.
42 + 24 = 66
Then we need to subtract the amount of taxes he paid for both jobs from the amount of money he earned. This will give us the total amount of money he earned after paying taxes.
375 - 66 = 309
Your answer is (B)

If he has 855.08 dollars after taxes and before taxes he had 1,100 dollars we need to find their difference. This will give us how much he had to pay to get to 855.08 dollars.
1,100 - 855.08 = 244.92
Your answer is (C)
