Final answer:
Rosa will make $220 and Devin will make $190.
Step-by-step explanation:
To calculate how much each employee will make, we need to consider their regular pay and overtime pay separately.
For Rosa, she will make $20 per hour for the first 8 hours of work, and time and a half ($30 per hour) for any additional hours. Let's say Rosa worked 10 hours:
- Regular pay: 8 hours x $20 = $160
- Overtime pay: 2 hours x $30 = $60
So Rosa will make a total of $160 + $60 = $220.
For Devin, the same calculation applies. Let's say Devin worked 9 hours:
- Regular pay: 8 hours x $20 = $160
- Overtime pay: 1 hour x $30 = $30
So Devin will make a total of $160 + $30 = $190.
