In the following problem, use the percentage method of withholding, FICA rate of 6.2%, a Medicare rate of 1.45%, an SDI rate of 1%, and a state withholding tax rate of 3.4%.

Maria is presently paid $375 a week. She is married and has two children, therefore she is claiming four withholding allowances. She is informed by her supervisor that starting next month her pay period will be changed to once a month. Knowing this, she plans on saving $100 a month in her credit union, $20 a month contribution to United Way, and $10 a month in dues. In addition to her $375 weekly pay, Bev will also receive a 6% commission on all her sales over $6000. She estimates her sales for the next month to be $25,000 with returns of $5000. Determine her estimated net pay.
