Joe earns $4,100 per month and pays $870 each month in rent. Approximately what percent of his money is spent on rent?
Scorpion4ik [409]

if we take 4100 to be the 100%, what is 870 off of it in percentage?


\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 4100&100\\ 870&x \end{array}\implies \cfrac{4100}{870}=\cfrac{100}{x} \\\\\\ 4100x=87000\implies x=\cfrac{87000}{4100}\implies x=\cfrac{870}{41}\implies x\approx 21.22
