[Question]Mrs. Smith wanted to buy wears worth $500. She went to a boutique with the $500 but by the time she had picked out everything she liked, she realized that she would need two-fifths more money than she had. If the shop owner gave her a discount of 15%, how much more money will she still need?
[Answer]Two fifths of $500 is (2 / 5) * $500 = $200. She needed $200 more than $500 which is $200 + $500 = $700. 15% of $700 is (15 / 100) * $700 = $105. She was given a $105 discount so she has to pay $700 - $105 = $595. She would still need $595 - $500 = $95. The answer is 95.

Asia saved $350 - $140 = $210 on the dress. That means she saved $210 / $350 = 0.60 or 60% off on the dress. The answer is 60.
