Question

The drug store is having a sale where all merchandise is 1/4 off. A woman buys $30 of merchandise at a sale price. What would she have had to pay at the regular price?

Answer 1

$30 = 75%, so divide it by three and you got your 25%, which ia $10.
$10 * 4 = $40.

So the answer is $40.

Hope this helps.
