Question

The number of girls in the Middle School Cyber Club was 6 more than double the number of boys, and in total there were 48 middle school students in the Cyber Club.

Answer 1

g = number of girls;

b= number of boys

we know that: g= 6+2b

and that: g+b= 156 kids in total

so we may write g+b=(6+2b)+b=6+3b

but g+b= 156

so 6+3b = 156 => 3b= 156-6=150 => b=150/3=50 => b = 50 (number of boys)

g= 6+2b= 6+2 x 50= 106 => g =106 (number of girls)
