Select the correct answer.

Question 3 options:

4 dollars

6 dollars

5 dollars

Answer 1

To find Erin's hourly rate, we divide the total amount earned by the total number of hours worked.

Last week, Erin earned $25 for 5 hours of baby-sitting, giving her an hourly rate of $25/5 = $<<25/5=5>>5 per hour.

This week, Erin earned $40 for 8 hours of baby-sitting, giving her an hourly rate of $40/8 = $<<40/8=5>>5 per hour.

So, Erin's hourly rate in whole dollars is $5. Therefore, the correct answer is 5 dollars.
