The number of girls at middle school Cyber summer camp was six more than twice the number of boys. The total of 156 middle school at the camp. How to use the 5-d process? To find the number of boys and girls at the camp.
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)
