Multiplication of Decimal Fractions

APPLICATIONS :When you get your paycheck, your employer is required by law to withhold some of your money in taxes. Your gross pay is your salary or wages before taxes. Your net pay is what is left over. Taxes such as federal withholding, social security, and retirement are just a few that will be taken out.

Let’s say Jeff works for $12.75 per hour and works a 40 hour week. His taxes taken out are as follows : federal withholding = 0.138 , social security = 0.0765, and retirement = 0.065. Find Jeff’s gross and net pay. ( round to pennies )
