To find Holly's income tax rate, we can use the gross pay and the income after taxes.
- First, we need to determine how much tax Holly paid. We can do this by subtracting her income after taxes from her gross pay:
\[ \text{Tax paid} = \text{Gross pay} - \text{Income after taxes} \]
\[ \text{Tax paid} = 1475 - 1321.60 = 153.40 \]
- Next, we can calculate the tax rate by dividing the tax paid by the gross pay and then multiplying by 100 to convert it to a percentage:
\[ \text{Tax rate} = \left( \frac{\text{Tax paid}}{\text{Gross pay}} \right) \times 100 \]
\[ \text{Tax rate} = \left( \frac{153.40}{1475} \right) \times 100 \]
\[ \text{Tax rate} \approx 10.4% \]
Thus, Holly's income tax rate is approximately 10.4% to the nearest tenth.
