整式和其他的数学问题一样,在我们的日常生活中也有着广泛的应用,现举例说明.例1学校组织教师和学生到森林公园春游,每位教师的车费为x元,每位学生的车费为y元,学生每满100人可优惠2人的车费,如果该校七年级有教师15人,学生326人,则需要付给汽车公司的总费用为____.简析付给汽车公司的总费用应为教师的车费与学生的车费的和.此时教师的车费为15x元,而学生的车费为(326-6)y元=320y元.所以付给汽车公司的总费用为(15x+320y)元.
Like all other math problems, the whole formula has a wide range of applications in our daily life. Here is an example. Example 1 The school organizes teachers and students to visit Spring Forest. Each teacher’s fare is RMB x, and each student’s The fare is yyyyy. Students can enjoy a fare of 2 per 100 students. If there are 15 teachers and 326 students in the seventh grade, the total cost to be paid to the car company is ____. The total cost of the car company should be the sum of the teacher’s fare and the student’s fare. At this time the teacher’s fare is 15x yuan, and the student’s fare is (326-6)y yuan = 320y yuan. So pay the car The company’s total cost is (15x+320y) yuan.
