So from 3.80 to 2.85, is a difference of 0.95 or 95 cents.

now, if we take 3.80 to be the 100%, what is 0.95 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
3.80&100\\
0.95&p
\end{array}\implies \cfrac{3.80}{0.95}=\cfrac{100}{p}\implies p=\cfrac{0.95\cdot 100}{3.80}$
