Final answer:
To calculate Chris' state tax, subtract his exemptions from his total income to determine his taxable income. Then, multiply the taxable income by the state tax rate. Chris will owe $401.54 in state tax.
Step-by-step explanation:
To calculate the amount of state tax Chris will owe, we first need to determine his taxable income. His total income is $21,423, and he has exemptions for himself, his wife, and their son. To calculate the taxable income, we subtract the exemptions from his total income:
Total Income - Exemptions = Taxable Income
$21,423 - ($4,500 + $4,500 + $4,500) = $8,923
Next, we calculate the state tax by multiplying the taxable income by the state tax rate of 4.5%:
Taxable Income x State Tax Rate = State Tax
$8,923 x 0.045 = $401.535
Rounding to the nearest cent, Chris will owe $401.54 in state tax.
