The number of lines that can be formed for the next concert is 78.
Using the parameters given for our Calculation;
- Number of students = 156
- Numbers of students per line = 2
To obtain the number of lines that can be formed;
- Number of students / Number of students per line
Now we have;
Number of lines = 156 / 2 = 78
Therefore, the number of lines that can be formed is 78
