学习数学的目的在于应用.我们学习了一元一次不等式与一次函数以后,若将二者巧妙地结合起来,可以解决许多中考实际应用问题. 例1 (2004年四川省)某零件制造车间有工人20名,已知每人每天可以制造甲种零件6个或乙种零件5个,且每制造一个甲种零件可获利润150元,每制造一个乙种零件可获利润260元.在这20人中,车间 The purpose of learning mathematics is to apply. After learning one inequality inequalities and one function, if we combine the two ingeniously, we can solve practical problems in many middle schools. Example 1 (Sichuan Province, 2004) It is known that each person can manufacture 6 types of parts or 5 parts of type B per day, and that each piece of a type of part can be profited by 150 yuan, and each piece of type B can be profitable by 260 yuan.
