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?

h = 7 × 410 + 210
20

h = 7 − 410 + 210
20

h = 7 − 410 − 210
20

h = 7 + 410 − 210
20
