Final answer:
Mikayla worked a total of 35 hours over 5 days and earned $420. To find her hourly rate, divide the total earnings by the total hours, which results in an hourly rate of $12.
Step-by-step explanation:
To calculate Mikayla's hourly rate for tutoring, we need to divide the total amount she earned by the total number of hours she worked. Mikayla worked 7 hours each day for 5 days and earned a total of $420 working.
- First, calculate the total number of hours Mikayla worked: 7 hours/day × 5 days = 35 hours.
- Next, divide the total earnings by the total number of hours: $420 / 35 hours = $12 per hour.
Mikayla's hourly rate for tutoring is therefore $12 per hour.
