8折英文

discount 九折就是 10% discount 八折是 20% discount 依次类推 i will give you 10% discount 我将给你打九折

i'll give you 20% discount for all the items

当然是8折了，，，就是去掉20%

I'll give you 20% off for all items.I"ll give you 20% discount on all items.You can have all the items for 20% off.这几个都可以。注意英文没法把“八折”说出来，所以就说“降20%” ^_^

You can have an 80% discount for all the items.或 Every item here is 20% off.或 You can buy any item here at a discount of 80%.
