Today's math class, the teacher gave an example, the topic is:

The school organized teachers and students to visit the Science and Technology Museum. There are 100 students and 50 teachers. Admission to the Science and Technology Museum is for adults 10 yuan, with half price for children. Q: How much is the charge?

Xiaohong raised her hand, and the teacher ordered Xiaohong to answer on the blackboard. Xiaohong's formula is as follows:

10/2=5 (yuan)

100*5=500 (yuan)

50* 10=500 (yuan)

500+500= 1000 (yuan)

A: Its price is 1000 yuan.

The teacher said, "Well, is there any other way?" Xiaoyue raised her hand, and the teacher ordered Xiaoyue to answer on the blackboard. The formula for abortion is as follows:

( 100/2)+50

=50+50

= 100 (name)

100 *10 =1000 (yuan)

A: Its price is 1000 yuan.

The teacher said, "Very well, please come on stage and explain."

"I mean 100/2=50 (name) first. It means: because the adult fare is twice that of children, there are 100 children, and the required fare is equal to 50 adults. Add 50+50= 100 (name), that is, add teachers, one * * * has 100 "adults", and finally use100 *100 =1000 (. Abortion solution theory.

"Very well, thank you for your abortion, your explanation is very comprehensive. What we are learning today is' smart counting'. Ok, class is over. " The teacher said.
