Okay, here are the steps:
1) Federal tax withholding (from tables): $36
2) Social Security tax (6.2% of $628): $38.93
3) Medicare tax (1.45% of $628): $9.11
4) Medical insurance: $28
5) Union dues: $12
Total deductions: $36 + $38.93 + $9.11 + $28 + $12 = $124.04
Net pay: $628 - $124.04 = $503.96
So the deductions are $124.04 and the net pay is $503.96.
