Final answer:
Laura earned $552.16 that week through regular hours and a holiday shift.
Step-by-step explanation:
To calculate Laura's total earnings for the week, we need to consider her regular rate and the additional holiday shift.
First, let's calculate Laura's earnings for her regular hours:
- Multiply her regular rate of $9.86 by the number of hours she works per day: 8 hours/day * 5 days/week = 40 hours.
- Then, multiply the result by her regular rate: $9.86/hour * 40 hours = $394.40
Now, let's calculate Laura's earnings for the holiday shift:
- Multiply her regular rate by 2 to account for double time: $9.86/hour * 2 = $19.72/hour.
- Then, multiply the result by the number of hours she works on the holiday shift: 8 hours * $19.72/hour = $157.76
Finally, add Laura's earnings for her regular hours and the holiday shift: $394.40 + $157.76 = $552.16
Therefore, Laura earned $552.16 that week.
