Nancy is single, with an Adjusted Gross Income of $25,985. She has one exemption of $8200. What is the amount of tax due? $2301
Fudgin [204]
Take her gross income and subtract her exemption of 8200. The number you get is what she needs to pay tax on. I can't really go any further, I need a table of information to go off of to further the answer. Although assuming you would have a tax bracket, you would simply just read to the right and a value in the single column will be your answer. Sorry, not much to go off here :/.
