Julie is a math tutor. She charges each student $210 for the first 7 hours of tutoring and $20 for each additional hour. When the number of hours (h) that Julie spends tutoring a student is greater than 7 (h > 7), the equation that gives the amount (A) that Julie earns in dollars is A = 210 + 20(h + 7) A = 210 + 20(h - 7) A = -210 + 20(h - 7) A = 210 + (h - 7)/20. If Julie earns $410 tutoring one student, solve for the total number of hours she spent tutoring the student.


A.) 38

B.) 19

C.) 17

D.) 12

Verified Answer :

The best and most correct answer among the choices provided by your question is the third choice or letter C. The total number of hours is 17.

 For h>7 

C=210+20(h-7) 

C=210+20h-140 

C=20h+70, h>7 

410=20h+70 

20h=340 

h=17 hours
