近年中考试题出现了不少偏重考查同学们能力的新亮点,现就此作一些粗浅的归纳,将对同学们学习有所启发。一、利用数学建模解决问题例1 某工程队要招聘甲、乙两种工种的工人150人。甲、乙两种工种的工人的月工资分别为600元和1000元,现在要求乙种工种的人数不少于甲种工种人数的2倍,问甲、乙两种工种人数各招聘多少人 In recent years, there have been a number of new highlights of the examination papers that focus on the ability of the students. Now we have made some superficial inductions, which will inspire students. First, the use of mathematical modeling to solve problems Example 1 An engineering team to recruit A, B workers in two types of work 150 people. Workers A and B have monthly wages of 600 yuan and 1,000 yuan respectively. Now the number of workers required for type B is not less than 2 times the number of workers of type A, and the number of workers for type A and type of workers is about how many people are recruited.
