enrollment is a business seminar increased from 50 people to 62 people. what was the percent increase?

OLga [1]

well, it went up from 50 to 62, so it really went up by 12 folks.

if we take 50 to be the 100%, what is 12 off of it in percentage?

$\begin{array}{ccll} amount&\%\\ \cline{1-2} 50 & 100\\ 12& x \end{array} \implies \cfrac{50}{12}=\cfrac{100}{x}\implies \cfrac{25}{6}=\cfrac{100}{x} \\\\\\ 25x=600\implies x=\cfrac{600}{25}\implies x=24$
