Hello, thank you for taking the time to post your question!
You can just multiply the values together in order to find the value that it’s after!
Amount Withheld = Weekly Pay x Tax Rate
Amount Withheld = 276 x 0.0765
Amount Withheld = 21.11
It looks like that would be the first choice out of the list of options!
I hope that helps get you moving in the right direction! Feel free to reach out if you have any additional questions beyond that :)
