✔ 最佳答案
1) 15.7*5/10=7.85元2) 冇優惠下=30*5=150
有優惠下=30*4=120
獲得幾折=120/150*100%=80%
所以係八折。

1. $15.7 x ( 4 + 1 ) / 10 = $7.85
2. 原價 = $30 x 5 = $150
特價 = $30 x ( 5 - 1 ) = $120
折頭 = $120/$150 x 100% = 80% (八折)

1. 罐汽水平均售:(15.7x5) / 10
=$7.85
2.120/150 x 100%
=80%
=$7.85
2.120/150 x 100%
=80%
2007-12-18 7:12 am
1. 15.7x(5+1)/10=7.85 = 每罐汽水平均售7.85元
2. (30x4)/(30x5)x100%=80% = 八折
2. (30x4)/(30x5)x100%=80% = 八折
