3.8 What do you mean by subtracting one piece from 38, two pieces from 88 and three pieces from 158 for women's day underwear activities?

It is a marketing activity of the merchants. 38 yuan can buy one pair of underwear cheaply, 88 yuan can buy two pairs of underwear cheaply, 158 yuan can buy three pairs of underwear cheaply.

The more you buy, the more you spend, and the greater the discount. This is the consistent consumption routine of merchants. I suggest you carefully choose what suits you and consume rationally.
