最佳解答:
倘若莉莉將糖果盒中百份之三十顆的糖果取出,隨後再多取三顆, 盒中尚餘十一顆糖果。原本在糖果盒中共有多少顆糖果 ? 2)奥斯加在商塲內看見心愛的機械人, 標價六百五十元, 並宣稱有原價百份之三十五優惠(即六五折)。他很高興便給了二百二十七元五角給店主。但店主拒絕這宗交易。你知原因嗎 ? ______________________________________________________________ Let x be the originnal amount of candies in the box: x-(30%x+3)=11 x-0.3x-3.....=14 0.7x...........=14 ......x..........=20 ________________________________________________ 原價x: x(1-35%)=650 x...........=1000 _______ 因為$650已經是DISCOUNTED,即1000x(1-35%)=650 _ Oscar不知道650己經DISCOUNTED,而且他以為是35折(650x35%=227.5) so,the owner rejected the trade 2010-07-16 12:55:25 補充： Thank your for 001!
