各位好
不曉得這問題能不能在這問
是這樣的
Sigma七折如火如荼展開
折扣後150美金免運 可選一贈品刷(原價19美金) A要5折認購
A 訂單折扣後100美金
B 訂單折扣後25美金
C.訂單折扣後25美金
所以要如何計算A認購了5折贈品刷後,大家的金額變多少?
----------------------------------------------------
這是我的理解,不知道對不對
A要以5折認購贈品刷(原價19美金) 19x0.5=9.5
9.5分配給其他人
所以25+25-9.5=40.5
40.5/50=0.81
25x0.81=20.25
故分配後 A 訂單折扣後100美金
B 訂單折扣後20.25美金
C.訂單折扣後20.25美金
是這樣嗎?
真的很慚愧,我算了好久算不出來
請問有好心板友可以指點我一盞明燈嗎?
謝謝
Sigma好刷推薦:如果你的眼皮暈染範圍較小,或是眉毛跟眼睛距離較近,
眼線筆畫外眼線總覺得雙眼皮摺變小了
1.E15:可沾黑色眼影粉用壓的,壓上一條細細的眼線
2.E38:較小的暈染刷
3.E45:精細的小小暈染刷
4.E30:可上小範圍重色的鉛筆刷
5.3DHD:最出名的粉底刷(若是對底妝要求高標準,晃祐堂是個不錯的好選擇)
