Explanation:
Aaron earns $165,000. This is between $160,850 and $349,700.
The base amount for this level is $39,149.
The amount of $160,850 is 165000-160850 = $4,150.
Multiplying this amount by 33%, 0.33(4150) = $1369.50.
Adding this to the base amount, 1369.50+39149 = $40,518.50.
Computing this monthly, 40518.50/12 = 3376.541667 ≈ $3376.54.
