Donna earns $1,404 per week at her job. however, 19% of her income gets taken out in taxes, and 12% of her income gets taken out and put into her retirement account.
which is a reasonable estimate of the amount donna is left with each week after the money is taken out?

Amount of money that Donna earns per week = $1404
Percentage of money taken out from Donna's income as taxes = 19%
Then
Amount of tax deducted from Donna's income = (19/100) * 1404
                                                                           = 26676/100
                                                                           = 266.76 dollars
Percentage of money that is put into Donna's retirement account = 12%
Then
Amount of money that is
put into Donna's retirement account = (12/100) * 1404 dollars
                                                           = 16848/100 dollars
                                                           = 168.48 dollars
Then
Amount of money Donna is
left with each week after deduction = 1404 - (266.76 + 168.48) dollars
                                                         = 1404 - 435.24 dollars
                                                         = 968.76 dollars
So from the above deduction we can see that the amount of money that Donna is left with each week after deductions is $968.76. It can be rounded to $969.
