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 :/.
To solve this problem, we first need to find each of their hourly rates. We can do this by dividing the boxes by the number of hours. Using this method, we get that Jack wraps 14 boxes per hour and Walter wraps 12 boxes per hour. So, since the question has them working together, the rate is the sum of each of their individual rates per hour. Since we know that they work for t hours, we can multiply their combined rate by t (since in a job problem, job = time * rate). And, on the other end of the equal sign, since we know that they wrapped 65 presents, we put 65 there. The equation becomes:
(14+12)t = 65
Which simplifies to
26t = 65
