Question

For her tutoring services, Thuy charged Demi $10 per hour and $8 for books and supplies. Demi paid a total of $48.00. Which equation represents this situation?

Answer 1

First there is the charge of $10, that must be taken away. Then the rest can be divided by 8 to give the answer:
48-10 = 38
38/8 = 4.75

She brought 4.75 books and supplies,
Hope this helps! :)
