Answer: The withholding tax rate changes depending on how much the person is paid.
There is no single rate that applies to every person for every pay period if hours worked or tips/commissions paid are different every week.
Step-by-step explanation:
Above the examples chart there is a list of $-amounts "Over ..... But not over" To the right of that, you have a list of a base amount withheld and a % rate to be applied. Those are the % rates you are looking for.
Once you have a given "gross pay" to work with, you find out where that falls into the amounts given, select the base and %, then follow the steps as you see in the examples in the chart.
