Can someone please help
chubhunter [2.5K]

Answer:


Step-by-step explanation:

She has 28056 before any deductions are taken off. As far as the IRS is concerned every penny she earns is fully accountable for the 4 categories that she has to pay into.

The problem with the question is you are not told what is wanted. Do they want the income before or after the deductions have been made or do they want the accountable sum (28056)? I don't really know. 28056 is one possible answer.

Total deductions

  • Federal Tax     3780.90
  • State Tax           770.98
  • Medicare            406.81
  • SSI                     <u>1739.47</u>
  • All Deductions  6698.16

 Income = 28056 - 6698.16 = 21357.84

I think the answer you want is 28056

One answer it is not is 4*28056 = 112224. The tax is far too low for that kind of income.

Mark plans on taking 3 trips this summer. He'll drive 143 miles,138 miles , and 141 miles. Estimate the total miles he'll drive.
Deffense [45]
Lets round each distance to the nearest tens place, and then add them up to get an estimate. 143 rounds down to 140, 138 rounds up to 140, and 141 rounds down to 140. So: 140 + 140 + 140 = 420 miles
