Question 1108380
<br>
He withdrew 60% of the money from his savings and spent 80% of that amount on shoes.  So the $60 he had left was 20% of the 60% he withdrew.  20% of 60% is 12%; so $60 is 12% of his original savings.<br>
{{{0.12x = 60}}} -->  {{{x = 500}}}<br>
The amount of his original savings was $500.<br>
He withdrew 60% of his savings: {{{.60*500 = 300}}}<br>
He spent 80% of that amount on shoes: {{{.80*300 = 240}}}<br>
The shoes cost $24 each; the number of shoes he bought was {{{240/24 = 10}}}.
