Final answer:
Miguel will earn a total of $76.20 for 3 hours of mowing at $9.20 per hour and 6 hours of babysitting at $8.10 per hour.
Step-by-step explanation:
To calculate how much Miguel will earn for 3 hours of mowing and 6 hours of babysitting, we simply need to multiply his hourly rates by the number of hours worked in each activity and then add the two amounts together.
For mowing:
- 3 hours × $9.20/hour = $27.60
For babysitting:
- 6 hours × $8.10/hour = $48.60
Adding both amounts together gives us:
$27.60 (mowing) + $48.60 (babysitting) = $76.20
Therefore, Miguel will earn a total of $76.20 for 3 hours of mowing and 6 hours of babysitting.
