Final answer:
Heather must pay $19,641.51 in federal income tax based on her annual salary of $93,531 at a tax rate of 21%.
Step-by-step explanation:
The student's question is about calculating the amount of federal income tax that Heather, a school principal earning $93,531 a year, would have to pay if her tax bracket requires her to pay 21%. To find the amount of tax Heather must pay, we use the formula:
Tax amount = Income × Tax rate
In Heather's case, the calculation would be:
Tax amount = $93,531 × 0.21
Therefore, Heather's federal income tax payment would be:
Tax amount = $19,641.51
So, Heather will have to pay $19,641.51 in federal income tax.
