Half the students in Max's class volunteer at the local community center. 15 students do not volunteer.if there are 12 boys in Max's class , how many girls are in Max's class? I am having a brain freeze!

  • Math-please help!! -

    let the number of girls be x
    total in class = x+12
    number of students who do not volunteer
    = (x+12)/2
    but this is 15

    (x+12)/2 = 15
    x+12 = 30
    x = 18

    So there are 18 girls in the class.
