Question

Macy is tutoring students in mathematics during her summer break. She charges $20 for a 30 minute session and $35 for an hour. The graph shows the number of 30 minute and 1 hour sessions she needs to have in order to make $280.
During her first week of tutoring, she only has 1 hour sessions, but makes exactly $280. How many tutoring sessions did Macy have during the first week?

Answer 1

If she only had 1 hour sessions she had 8 sessions in the first week because if you do 35 times 8 you get 280.
