text: The question is very vague -- we're not given any information about what Bob's marital status (or rather whether he is withholding at a married or single rate) \n\nat 900 a week, he takes home $46800 annually.  6.2% of his 65k salary goes to Social Security ($4030) and 1.45% goes to Medicare (942.50).  $60027.50 left before figuring his tax percentage, which works out at 22% (but that's not a correct figure, as it doesn't figure in state taxes, personal exemption, and standard deduction)
