To calculate the amount of state tax Selina owes, we need to follow these steps:
1. Identify her gross pay and withholding allowances:
- Selina's gross pay for two weeks is [tex]$840.
- She claims one withholding allowance.
2. Determine the federal tax contribution:
- From the provided federal tax table, for a biweekly gross pay between $[/tex]820 and [tex]$840, the federal tax withheld for someone with one withholding allowance is $[/tex]77.
3. Calculate the state tax deduction:
- Selina's state tax deduction is 21% of her federal tax contribution.
- Therefore, the state tax owed is:
[tex]\[
\text{State tax owed} = 21\% \times \$77
\][/tex]
- Converting 21% to a decimal gives 0.21.
- Multiplying:
[tex]\[
\text{State tax owed} = 0.21 \times 77 = 16.17
\][/tex]
Thus, the amount of state tax Selina owes is [tex]\(\$16.17\)[/tex].
The correct answer is:
a. [tex]$\$[/tex]16.17$
