88+12=100(уч.)-стало во всех четырех классах

Answer 3

Calculating the Total Number of Students

To calculate the total number of students who joined the classes throughout the year, we can use the following approach:

1. Initial Number of Students: At the beginning of the year, there were 88 students in total across the four classes.

2. Students Joined Each Class: Throughout the year, 3 students joined each class.

Calculation

Using the given information, we can calculate the total number of students who joined the classes throughout the year:

- Initial Number of Students: 88 - Students Joined Each Class: 3

To find the total number of students who joined the classes, we can use the following formula: Total students = Initial students + (Students joined each class * Number of classes)

Substituting the values: Total students = 88 + (3 * 4) = 88 + 12 = 100

So, the total number of students who joined the classes throughout the year is 100.

Total Number of Students at the End of the Year

To find the total number of students at the end of the year, we can add the initial number of students to the total number of students who joined the classes throughout the year.

Total students at the end of the year = Initial students + Total students joined Total students at the end of the year = 88 + 12 = 100

Therefore, the total number of students at the end of the year is 100.
