We have to find the federal taxes that should pay Holly, a single taxpayer.
In the single table, we see that the taxes due will be given by
![4,453.5+(22)/(100)\text{ of the amount above \$}38,700](https://img.qammunity.org/2023/formulas/mathematics/high-school/knpze4pm1nlbg4ctjstxci5hve36izv32v.png)
The amount is $40,300, and applying the formula we obtain:
![\begin{gathered} 4,453.5+(22)/(100)(40,300) \\ =4,453.5+8,866 \\ =13319.5 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/p42pxkck7758prxte89phh1m7prm4ih1uk.png)
This means that the federal taxes due of Holly is $13,319.5.
