少付...其實即係計平左幾多la

720x(1-85%)
=720x 0.15

可少付幾元:
720-(720*0.85)
=720-612
=108(元)

可少付:
720x(1-85%)=720 x 15% =108(元)

八五折即85%。
可少付︰
720*(1-85%)
=720*(100%-85%)
=720*15%
=720*15/100
=$108
答︰可少付$108

2008-04-07 18:32:55 補充:
1-85%是因為︰
如果分兩part計就是︰
720*85%
=$612
只要付$612,那只要用720-612=$108
換句話︰
720*1-720*85%
拫據乘法分配性質就可以將條式變成720*(1-85%)
