He must pay $10,000 in income taxes.

Step-by-step explanation:

Hi, to answer this question we have to analyze the rate table find an interval where the amount earned is included:

Analyzing:

25% on taxable income over $36,250 to $87,850, plus

Our percentage is 25% because $36, 250 < $40,000 < $87,850

Now, we have to calculate the amount by multiplying Mr.Vasquez earnings ($40,000) by the percentage expressed in decimals ( 25/100 = 0.25)

Mathematically speaking  

40,000x 0.25 = $10,000
