Each week, Alice's gross salary is $\$ 9.00$ an hour for the first 40 hours she works and $\$ 15.00$ an hour for each hour she works in excess of 40 hours.

Which of the following expressions represents Alice's net pay in a week that she works $x$ hours where $x>40 ?$ $$\begin{array}{l}{\text { (A) } 0.23(15 x-240)-20} \\ {\text { (B) } 0.23(15 x-220)} \\ {\text { (C) } 0.77(15 x-240)-20} \\ {\text { (D) } 0.77(15 x-220)}\end{array}$$

Net Pay Computation

Net pay is the amount an employee takes home after all deductions are subtracted from the gross pay. It is obtained by formulating an expression that starts with the gross earnings and subtracts both the fixed and percentage-based deductions.

Deductions

Deductions include any amounts subtracted from the gross pay, which can be both a fixed fee (such as a fixed insurance cost) and percentages of the gross salary (such as taxes). They are critical to arriving at the final net pay an employee receives.

Gross Pay Calculation

Gross pay refers to the total earnings before any deductions are made. It is computed by summing up the regular wages for a fixed number of hours and, if applicable, additional wages for overtime hours worked at a different rate.

Overtime Pay

Overtime pay is calculated by applying a higher hourly rate for hours worked beyond the standard or normal working hours. This extra rate compensates employees for additional hours worked above a predetermined limit.
