A tutor charges $25 dollars for private tutoring and $18 for group tutoring. In one week a tutor earn $265 for 12 students. How many private and group sessions were there?

I will assume these says   12  SESSIONs

 

Let x = individual students

then 12- x  = group sessions

 

Income from individuals    x    is   25 x

Income from group  is                18(12-x)         added together this equals  265

 

25 x    +  18 ( 12-x)   = 265        solve for x , the individuls, then group# =   25-x
