<em />

<em>Response-</em>

Since we are using percents we can make an equation out of this question

$\frac{85}{100}=\frac{816}{x}$

$\frac{85}{100}$ is the way we write percents in math as a fraction

and $\frac{816}{x}$ is the part and whole you gave us

$\frac{85}{100}=\frac{816}{x}$ cross multiply

$85x=81600\\divide\\x=960$ students are in the school

$\huge\blue{\mid{\fbox{\tt{ANSWER}}\mid}}$

$960$ students at Y'vans school
