The marginal tax rate is the additional tax payable for an additional dollar of taxable income.

$48,000 taxable income falls in the 25% bracket (taxable incomes between $33,950 and $82,250), therefore the marginal tax rate is 25%.

The average tax rate is the tax payable divided by the taxable income.
The tax payable is $8187.50 calculated according to the table. The tax authorities usually round to the nearest dollar, which makes $8188.
The taxable income is $48,000.
The average tax rate is therefore $8,188/$48000= 17.1%
