Answer: $25
Step-by-step explanation: Since there are three students you multiply 15 by 3 (15×3).
This gives you 45 (15×3 = 45)
you then subtract $45 from $120 (120 - 45).
This gives you 75 (120 - 45 = 75).
Finally you divide 75 by 3 (75÷3) since there are three students who pay for the lessons.
75÷3= 25
Therefore each person pays $25 just for the lesson.
to prove it: 25×3= 75. 15×3=45. Add both answers together and you should get 120.
