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.
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!

This is easy like the Cleveland browns
Get the EXTRAMOSTBESTEST FROM LITTLE CEASERS FOR JUST 6 BUCKS
I worked it out.
1/2(x+12)= 15
Then, divide 1/2(x+12) by 1/2 and the 15 by 1/2
x+12= 30
(x+12)-12 30 -12
x= 18
1/2(x+12)= 15
Then, divide 1/2(x+12) by 1/2 and the 15 by 1/2
x+12= 30
(x+12)-12 30 -12
x= 18
