Below I will illustrate how to solve this kind of problem through a concrete example.
Suppose there is a store that carries out promotional activities, and it is stipulated that for every five items purchased, you can get a free gift of 1. Now we have to calculate how many gifts we can get after buying 10 items.
First, we can turn the problem into a mathematical expression. If you can get 1 gift for every 5 items you buy, then the number of gifts you can get when you buy 10 items is:
The number of gifts = (the number of goods purchased/the number of gifts available for each purchase of X items)
In this example, the number of goods purchased is 10, and the number of gifts available for every five items purchased is 1. Therefore, we can substitute them into the formula to get the answer.
According to the formula, we can calculate:
Number of gifts =( 10/5)=2.
Therefore, after purchasing 10, you can get 2 gifts.
It should be noted that if the number of purchased goods is not a multiple of 5, then we can only calculate the number of gifts in proportion. For example, if we buy 8 items, the number of gifts we can get is:
The number of gifts =(8/5)= 1.6, but we can't get 1.6, so the actual number of gifts will be less than 2.
The purpose of buying math and giving some gifts;
The main purpose of buying some gifts for math is business promotion and preferential strategies. Merchants can attract more customers to buy goods by means of promotion, and at the same time, they can also promote customers' consumption and purchase intention. This kind of promotion is very common in commercial activities and has important practical application value.
First of all, buy a few and get a few free promotions can stimulate customers' desire to buy. When customers know that they can get extra gifts by buying a certain number of goods, they often have psychological motivation and feel that buying these goods is more cost-effective, thus increasing their willingness to buy. This promotion method has been applied in many fields, such as supermarkets, shopping malls, online shopping and so on.
Secondly, buying a few and getting a few free promotions can help businesses increase sales. In the fierce market competition, businesses need to attract customers and increase sales through various means. Buy a few and get a few free promotions can make customers feel that they have benefited, thus increasing their willingness and quantity to buy. This can not only increase sales, but also increase customers' trust and loyalty to businesses.
