The solution to how to calculate everyone's class expenses is as follows:

For example, 80 yuan a class, there are many people who get a commission. For example, if there are more than five people, the headcount fee will be calculated. If there are 10 children, the income of the whole class is: 80+5 * 5 = 105 yuan.

Class fees depend on the situation in different regions. Pay attention to the high fees for education, otherwise the fees will be low. My art class is very cheap. Some students organize art classes for 25 yuan for two hours at a time.
