To find the amount of state tax Selina owes, let's follow the steps below:
1. Identify the gross pay and federal tax contribution:
- Selina has a gross pay for two weeks of \[tex]$840.
2. Determine the federal tax withheld:
- From the federal tax table provided, for biweekly earnings of \$[/tex]840 and a single person claiming one exemption, the federal tax withheld is \[tex]$98.
3. Calculate the state tax percentage:
- The state tax deduction is 21% (0.21) of her federal tax contribution.
4. Calculate the state tax:
- Multiply the federal tax withheld by the state tax percentage to find the state tax amount:
\[
\text{State Tax} = \text{Federal Tax Withheld} \times \text{State Tax Percentage}
\]
Substituting in the given numbers:
\[
\text{State Tax} = 98 \times 0.21 = 20.58
\]
Thus, the amount of state tax Selina owes is \$[/tex]20.58.
