Final answer:
Gloria owes $2,800 in income tax.
Step-by-step explanation:
To calculate Gloria's income tax, we need to determine her taxable income and apply the relevant tax rates. Since Gloria earns $30,000 per year, her taxable income is $30,000. Here's how to calculate her income tax:
- Calculate the tax on the income up to $20,000 at a rate of 8%. The tax on this portion is $20,000 * 0.08 = $1,600.
- Calculate the tax on the income between $20,001 and $30,000 at a rate of 12%. The tax on this portion is ($30,000 - $20,000) * 0.12 = $1,200.
- Add the two calculated taxes to get the total income tax owed: $1,600 + $1,200 = $2,800.
Therefore, Gloria owes $2,800 in income tax.
