Question

Lisa charges $25 for private tutoring and $18 for a group tutoring session. One day in January, Lisa made $265 from 12 students. How many students of each type did Lisa tutor?

Answer 1

• 5 group session
• 7 private tutoring

Explanation:

Let p represent the number of private-session tutoring students. Then (12-p) is the number of group-session students. Her total revenue is ...

25p +18(12 -p) = 265

7p + 216 = 265 . . . . . . . simplify

7p = 49 . . . . . . . . . . . . . subtract 216

p = 7 . . . . . . . . . . . . . . . . divide by 7

Lisa tutored 7 students privately and 5 in group session that day.
