Question

Julie is a math tutor in the academic center. She charges $210 for the first 7 hours of tutoring and $20 for each additional hour of tutoring. If she earned $410 tutoring 1 student, how many total hours did she spent tutoring the student? Which of these equations represents this problem?

Answer 1

17 hours
$410-$210/20=17 hours

Answer 2

17 hours.

410=20x+210

Subtract 210 from 410 and get 200. Then divide 200 by 20 and get 10. Add 10 hours to the 7 original hours and get 17.
