Tracy charges $10 plus $12 per hour to babysit. If she got paid at $106 how many hours did she work?

Question

HELPPPPP PLEASE MATH TEST TOMORROW 

Answer 1

h represents the number of hours Tracy worked

 

pay = $10 + $12h

$106 = $10 + $12h     subtract 10 from both sides

$96 = $12h                  divided both sides by 12

8 = h

 

Tracy worked by 8 hours.
