20% discount analysis: I spent four yuan to buy five things, the unit price was A, the original price was 5*a, and now I bought 4*a, and 4*a divided by 5*a=0.8, which is 20% discount.

On the premise of "200 yuan return 100 yuan", X represents the consumption amount, and N and A in the formula need to be brought into the calculation according to the activity amount. If in this activity, the consumer only bought a dress of 399 yuan, this formula can be used to calculate that the consumer enjoys 7.5 fold.

In addition to accurately calculating the discount, Ms. Wang, a provincial shopping expert, also suggested that "when participating in coupon rebate activities, you should buy more favorite goods with the least cash, and it is most important to arrange the order of purchasing goods." She said, if you want to buy a pair of pants for 549 yuan. However, the strength of the pants coupon is to buy "200 RMB 150" and return your 300 yuan coupon as required.

Then you chose a shirt with a price of 369 yuan at the mall, and you paid more in cash and 69 yuan. The total cost is 6 18 yuan, which is equivalent to 6.7% discount. But if you buy a shirt with a coupon rebate of "100 to 100" first, and then buy a product that exceeds 300 yuan's, suppose the price of these two products is 7 12 yuan.

At this time, you can buy pants with 600 yuan's coupons. So, in the end, I spent 7 12 yuan on 126 1 yuan, so I enjoyed a 5.6% discount. However, first of all, we must understand the activity law of shopping malls. For example, some shopping malls stipulate that different activities cannot be combined, so the coupon of "100 return 100" cannot be used to buy pants.

The difference between buy one get one free and 50% discount.

Buy one get one free is not the same as a 50% discount, because buying one get one free will expand production, generate benefits and make funds flow quickly. A 50% discount will not reduce the attractiveness, but will reduce the production capacity. The flow of funds has slowed down.
