well, from 354000 to 414180, their difference is 414180 - 354000 = 60180.
if we take 354000 to be the 100%, what is 60180 off of it in percentage?
[tex]\begin{array}{ccll}amount&\%\\\cline{1-2}354000&100\\60180&x\end{array}\implies \cfrac{354000}{60180}=\cfrac{100}{x}\implies \cfrac{100}{17}=\cfrac{100}{x}\\\\\\100x=1700\implies x=\cfrac{1700}{100}\implies x=17[/tex]
