怎么个计算方法?
是这样的吗 ($5000-$1000)x1.13=$4,520
相当于是$4,520/($5000x1.13)=0.80
也就是说是如果刚好买到$5,000就是税后20%OFF?
如果买到$7000,那么就是($7000-$1000)x1.13=$6,780
相当于是$6,780/($7000x1.13)=0.86
也就是说是如果刚好买到$7,000就是税后14%OFF?

要是买到$9,500,那么就是($9500-$1000)x1.13=$9,605
相当于是$9,605/($9500x1.13)=0.895
也就是说是如果刚好买到$9,500就是税后10.5%OFF?

这时估计FS的SALE就会千方百计让你买些没用的$500刀好凑足1W了:flaming:
最近买东西老是算错数,不知道这样计算对不对?团长帮忙算算?
