so, the count went down from 850 to 500, or 350 units.

if we take the 850 to be the 100%, what is 350 in percentage off of it?


\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 850&100\\ 350&x \end{array} \implies \cfrac{850}{350}=\cfrac{100}{x}

solve for "x".
