Final answer:
Sara Wu earns $15.30 per hour for her regular hours and $22.95 per hour for overtime. She worked 38 hours at her regular rate and 8 hours overtime, for a total earning of $765.00 last week.
Step-by-step explanation:
Sara Wu earns an hourly rate of $15.30 and she receives time and a half for overtime. Last week she worked 38 hours at her regular rate and 8 hours of overtime. To calculate her total earnings, we need to multiply her regular hours by her hourly rate and then add her overtime earnings. The overtime rate is 1.5 times her regular hourly rate, so we will calculate that as well.
First, let's calculate her regular earnings:
38 hours × $15.30/hour = $581.40
Now, let's calculate her overtime earnings:
Overtime hourly rate = 1.5 × $15.30/hour = $22.95/hour
8 hours of overtime × $22.95/hour = $183.60
Lastly, add her regular earnings to her overtime earnings to find her total earnings for the week:
Total earnings = $581.40 (regular) + $183.60 (overtime) = $765.00
