Answer:$1,825
Explanation:
Based on the single tax rate schedule, of the additional $10,900 of taxable income, $9,000 is taxed at 15% (the increase $31,375 to $42,275) and the remaining $1,900 ($38,650 minus $37,650) is taxed at 25%. To summarize, ($9,000 × 15%) + ($1,900 × 25%)
= $1,350+$475
=$1,825
The income tax from second job increases her tax liability by $1,825.
