To solve this problem, we need to calculate Alice's regular pay, overtime pay, and gross pay for the third week of March. Here are the steps:
- Regular Pay Amount: Since Alice worked 38.75 hours, which is less than 40 hours, all her hours are considered regular hours. Multiply the total hours worked by her hourly rate.
- Overtime Pay: Since Alice did not work more than 40 hours, there are no overtime hours, and thus the overtime pay is $0.
- Gross Pay: The gross pay is simply the sum of the regular pay and the overtime pay.
Since Alice worked \( 38.75 \) hours, which is less than the overtime threshold of \( 40 \) hours, all her hours are considered regular hours. The regular pay can be calculated as follows:
\[
\text{Regular Pay} = \text{Regular Hours} \times \text{Hourly Rate} = 38.75 \times 13.50 = 523.125
\]
Rounding to the nearest cent, we have:
\[
\text{Regular Pay} = \$523.12
\]
Alice did not work any overtime hours since her total hours worked are less than \( 40 \). Therefore, the overtime pay is:
\[
\text{Overtime Pay} = 0
\]
The gross pay is the sum of the regular pay and the overtime pay:
\[
\text{Gross Pay} = \text{Regular Pay} + \text{Overtime Pay} = 523.125 + 0 = 523.125
\]
Rounding to the nearest cent, we have:
\[
\text{Gross Pay} = \$523.12
\]
- Regular pay amount: \( \boxed{523.12} \)
- Overtime pay: \( \boxed{0.00} \)
- Gross pay: \( \boxed{523.12} \)
