At the beginning and end of the year, many shopping malls are offering discounts. Taking this good opportunity, my parents and I went to XX Shopping Mall.

On the second floor, we took a fancy to a suit, and its price tag was 520 yuan. The salesman said, "It's time to clear the warehouse at the end of the year. Over 200, you can choose to get a 20% discount or return to 160. Both are similar. "

Is it really similar? I have such a problem in my mind. If you choose a 20% discount, you need 520× 0.8 = 4 16 yuan. And if it exceeds 200, it will return to 160? We have to pay 520 yuan first, and then we will get a coupon of 160× 2 = 320 (yuan), so we actually spent 520-320=200 (yuan). Compared with 200,416, the second one is of course better.

But after getting the coupon? If you buy something from 320 yuan again, you can return it to 160 yuan, and the rebate of this 160 yuan is only 200- 160 = 40 yuan. If you fill in this 40 yuan shopping form, you can return it to 160 yuan. Don't you have a crush? But if you really do this, you will fall into a bottomless pit and spend 200 times 160, 200 times 160 ... you will never spend the rest of the money.

It suddenly occurred to me that what I bought was never as good as what I sold. Merchants really try their best to make money!
