The gross income of david vaughn is $785 per week. his deductions are $42.25, fica tax; $90.33, income tax; 2% state tax; 1% city tax; and 3% retirement fund. what is his net income for one week?

Vaughn's net income will be the gross income minus any deductions. (2% of 785 is 15.70, 1% of 785 is 7.85, and 3% of 785 is 23.55.)

It will be easier to add together all the deductions, and then subtract that sum from 785:

42.25 + 90.33 + 15.70 + 7.85 + 23.55 = 179.68
785 - 179.68 = 605.32
