I have attached federal tax table is for biweekly earnings of a single person.
Answer:
state tax Selena owes = $16.8
Explanation:
1- getting the Federal tax:
We are given that:
her biweekly salary = $840
her claimed allowance = 1 exemption
Using the attached table, we can deduce that:
federal tax = $80
2- getting the state tax:
We know that the state tax is 21% of the federal tax.
This means that:
state tax = 21% * federal tax
state tax = 0.21 * 80
state tax = $16.8
Hope this helps :)
