Last year, our family of three were still "shopping" in New Century Shopping Mall. At that time, more than 500 coupons were sent to 500 yuan. First, I bought my father a woodpecker coat with 1880 yuan and gave him a shopping voucher with 1500 yuan. We didn't waste too much. We spent 478 yuan on a black Nike sportswear, and 488 of the remaining 1 0,000 yuan on a back-to-back spring and autumn costume. Finally, I spent 398 yuan to buy Apple jeans (because it was a shopping voucher, I didn't have any change, I was dissatisfied with 500 yuan, and I also received a coupon from 500 yuan). How much cheaper? 478+488+398= 1364 (yuan)-This is the money you need to spend when there is no discount. 1364/3244, the discount is about 42%.
I have done clothing business before my menstruation, and I also know the relationship between the purchase cost and the sales price of clothing. The purchase price of clothing generally only accounts for 20%~30% of the suggested retail price. With the intensification of competition and the promotion of shopping malls, in order to maintain profits, merchants or manufacturers continue to raise the suggested retail price of clothes. As a consumer who saw on TV a few days ago said, the suggested retail price of a pair of nylon trousers of the same style of a certain brand was only 299 yuan three years ago, and this year's price tag has become 999 yuan. Based on this calculation, the purchase price is only about 10%~20% of the market price. Even if the discount is 40% to 20%, merchants can still earn 30% to 50% gross profit.
Faced with various concessions, many people rushed to buy shopping, the flow of people in shopping malls increased, and the sales of goods also increased rapidly. Just when the flow of people is three times as usual, another math problem comes. Suppose a commodity is sold at a 10% discount when there is not much traffic at ordinary times. 10% off the purchase price, 2% off, and 7% of the marked price becomes gross profit. Although the same product may only earn 30% to 50% when "you get a 500 yuan coupon for over 500 yuan" now, the sales volume is at least three times as high as usual. Calculated by 30% gross profit and triple sales, 3×3=9, compared with the usual 70% gross profit, you can earn 30% more in one day. Although the gross profit margin of each product sold in this way has decreased, the gross profit has increased due to the increase of sales volume, and because of the large sales volume, the capital turnover has been accelerated and additional income has been brought.
There are mathematics in commodity pricing and promotion, mathematics in shopping consumption, mathematics in house decoration, mathematics in sweater weaving ... In short, mathematics is everywhere in real life!
