so the difference is 333.96 - 253 namely 80.96.
now, if we take 253 to be the 100%, what is 80.96 off of it in percentage?
[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 253&100\\ 80.96&x \end{array}\implies \cfrac{253}{80.96}=\cfrac{100}{x}\implies 253x=8096 \\\\\\ x=\cfrac{8096}{253}\implies x=32[/tex]
