✔ 最佳答案
40% off means 40% free
so it is sold at 60% of marked price

in your question, what is the discount
= how much you saved = 1800 x 40% = 720 discount
but the carpet still costs you 1800 x 60% = 1080

乘(1-40%) is the price after discount
x 40% is the discount

discount is the new value - orginal value

英文的40% off (discount percentage)是原價減百分之四十
中文的六折是售價為原價的百分之六十

discount = marked price - selling price = marked price x discount percentage

所以是 1800 x 40%

1800 x (1 - 40%) 是售價

因為 10% off =中文的9折
20% off=中文的8折

如此類推........
參考: Hope I can help you
