Answer:
Given that,
Taxable income = $75,000
Interest from an investment = $10,000
Using the U.S tax rate schedule in 2017
(a) Federal tax will he owe = $5,226.25 + 25% × ($75,000 - $37,950)
= $5,226.25 + $9262.5
= $14,488.75
(b) [tex]Average\ Tax\ Rate = \frac{Total\ Tax}{Taxable\ Income}[/tex]
[tex]Average\ Tax\ Rate = \frac{14,488.75}{75,000}[/tex]
= 19.32%.
(c)[tex]Effective\ Tax\ Rate = \frac{Total\ Tax}{Total\ Income}[/tex]
[tex]Effective\ Tax\ Rate = \frac{14,488.75}{75,000 + 10,000}[/tex]
= 17.05%
