为了更好地培养学生“运用所学知识解决简单的实际问题”的能力,通过把实际问题抽象成数学问题,再用数学知识解决实际问题,使学生进一步理解数学的应用价值,近年来各省市中考试题中不断涌现出新颖别致的应用性问题.本文就如何运用不等式知识,解中考应用性问题举例解析如下.例1(2003年四川省中考题)东风商场文具部的某种毛笔每支售价25元,书法练习本每本售价5元,该商场为促销制定了两种优惠 In order to better cultivate students’ ability to “use what they have learned to solve simple practical problems”, by abstracting practical problems into mathematical problems and using mathematical knowledge to solve practical problems, students can further understand the application value of mathematics. There are new and unique application problems emerging from the mid-term exam questions. This article will give an example of how to apply the inequality knowledge to solve the application problems of the midterm exam. Example 1 (Sichuan Province Exam Questions in 2003) Some writing brush of the Dongfeng Mallery Department Price 25 yuan, calligraphy book cost 5 yuan per book, the mall developed two promotions for the promotion
