Question

What is the percent change from 112 to 96

Answer 1

well, the change is just 112 - 96 = 16.

now if we take 112 as the 100%, what's 16 off of it in percentage?

`\begin{array}{ccll} amount&\%\\ \cline{1-2} 112 & 100\\ 16& x \end{array} \implies \cfrac{112}{16}~~=~~\cfrac{100}{x} \\\\\\ 7=\cfrac{100}{x}\implies 7x=100\implies x=\cfrac{100}{7}\implies x\approx 14.29`
