The 80 8th graders took a trip. The boys numbered 16 fewer than twice the number of girls. How many of the eighth graders are girls?

g + 2g - 16 = 80

3g = 96

g = 32

To solve this problem, we can set up an equation using the given information. Let's assume the number of girls is represented by the variable "g."

According to the problem, the boys numbered 16 fewer than twice the number of girls. We can express this as:

Boys = 2g - 16

We also know that the total number of eighth graders is 80. Therefore, the sum of boys and girls should equal 80:

Girls + Boys = 80

Now, let's substitute the expression for boys (2g - 16) in the equation:

g + (2g - 16) = 80

Simplifying the equation:

3g - 16 = 80

Adding 16 to both sides of the equation:

3g = 96

Finally, divide both sides by 3 to solve for g:

3g/3 = 96/3

g = 32

Therefore, there are 32 girls among the 80 eighth graders.
