Hmmm the increase, wel is just the difference 367 - 312, which is 55.

now, if we take 312 to be the 100%, what is 55 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
312&100\\
55&p
\end{array}\implies \cfrac{312}{55}=\cfrac{100}{p}\implies p=\cfrac{55\cdot 100}{312}$
