Irina-Kira [14]

$ 2772 is paid in state income tax

<em><u>Solution:</u></em>

Given that, Tina lives in a state that charges her 4.5% state income tax on her federal taxable income

Federal taxable income = $61,600

<em><u>To find: Amount paid by Tina in state income tax</u></em>

Tax rate = 4.5 %

<em><u>Which means, 4.5 % of $61,600 is paid as tax</u></em>

Tax\ Rate = 4.5 \% \text{ of } 61600

Here, "of" means multiplication or product

Tax\ Rate = 4.5 \% \times 61600\\\\Tax\ Rate = \frac{4.5}{100} \times 61600\\\\Tax\ Rate = 0.045 \times 61600\\\\Tax\ Rate = 2772

Thus $ 2772 is paid in state income tax
