The calculation method of clothing discount price is as follows: discount: subtract the percentage from the original number. That is, discounts, when buying and selling goods, are priced according to a certain proportion of the original price, such as 10%, 10% or 10%, 50% or 60%. For example, 100 is 50% off for 50 yuan, 60% off for 60 yuan and 70% off for 70 yuan. For example, a dress in 70 yuan is 50% off, and 70*0.5=35 yuan. Simply put, a few discounts are multiplied by a few tenths. A 15% discount on a 650 yuan dress is 650*0.85, and the figure obtained is the price to be bought and sold, and then the price before the discount is subtracted from the discounted price, and the remaining figure is the saved price.
