Revealing The Mystery Of "Return Ticket" Of Clothing Business

"299 yuan to 300 yuan coupons", "full 1000 yuan to send 1000 yuan clothing", "full 900 yuan to reduce 300 yuan cash"......

At the end of the year, the major shopping malls in the island city once again launched a promotional frenzy. All kinds of discount methods such as "full reduction", "full gift" and direct discounts were endless, which made many consumers call it in a fog, and it was not clear how much they could get.

A mathematical expert released the formula for coupon coupons, which showed that "300 yuan to 150 yuan in cash" appears to be half off, but in fact, consumers will never get the theoretical discount, and the discount of rebates will be greatly reduced.

Set formulas to be true.

How can it be cost-effective?

A clothing counter in a shopping mall is engaged in the activity of "300 yuan to 150 yuan in cash". The salesperson enthusiastically said, "we are now equal to half off preferential activities, which is especially cost-effective."

But is this really the case? When the counter turned around, it was found that all costumes ended with "8" and "9", and it was difficult to get enough 300 yuan or 300 yuan.

In order to figure out the scope of the discount, a mathematical formula is put forward by the mathematical expert: (N-N/300*150) /N, which is based on the activity of "300 yuan to 150 yuan", N represents the amount of consumption, while N/300 needs integer numbers, and the 300 and 150 of the formula need to be brought into account according to the amount of activity.

If in this activity, the consumer only buys a clothing of 439 yuan, the formula can be used to calculate that the consumer enjoys 34.2% off.

The shopping master Lin said, "to participate in the coupons, we must arrange the order of purchase and try to buy more products with the least cash."

If you want to buy a pair of A brand shoes, the price is 549 yuan.

But the strength of A brand is to buy "200 return 120", and return 240 yuan coupons according to regulations.

Then you picked up a 269 yuan B brand T-shirt in the shopping mall, and you paid more than 29 yuan in cash. The total cost was 578 yuan and 818 yuan, equivalent to thirty percent off.

If you buy a B T-shirt with the strength of "200 return 200", buy a product of more than 400 yuan, assuming that the purchase of the two items costs 612 yuan.

At this time, you can take 600 yuan coupons to buy shoes.

In the end, it cost 612 yuan to buy 1161 yuan of goods, close to half off.

The total cost is only 34 yuan more than the original shopping method, but it can buy more than 343 yuan products.

If it's a return activity, choose a small activity as little as possible, such as "100 return to 40 yuan" is better than "200 yuan back to 80 yuan".
