Answer:  Total number of students will be 112.

Step-by-step explanation:

Since we have given that

The ratio of boys to girls in the top 10% of their class at Bixby High School was

3:5

So, Let the number of boys be 3x

Let the number of girls be 5x

According to question,

\frac{3x+6}{5x+2}=\frac{2}{3}\\\\3(3x+6)=2(5x+2)\\\\9x+18=10x+4\\\\18-4=10x-9x\\\\14=x

So, total number of students will be

3x+5x=8x\\\\8\times 14=112

Hence, Total number of students will be 112.

I believe it could be any number because:

let y=any number

x^2+10x+y=16+y

x^2+10x+y-y=16+y-y

x^2+10x=16

you can add any number to both side and not change the solution.
