  A.  $16,079

Step-by-step explanation:

You are given the income of a married couple and the tax table applicable to married couples. To find the amount of tax owed, you first find the applicable line in the table, then do the computation it tells you.

The applicable line for an income of $110,000 is the one that says ...

  "77,401 to 165,000"

The left (Tax Rate) column of that line has "22%", and the right (Tax Owed) column tells you the computation you need to make.

You find "the excess over $77,400" by subtracting that amount from the $110,000 income:

  the excess over $77,400 = $110,000 -77,400 = $32,600

__

Then the tax owed is 22% of this amount plus $8907:

  tax owed = $8,907 + 0.22 × 32,600

  = $8,907 + 7,172

  tax owed = $16,079

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
