Respuesta :
For this case we have to:
If there are 26 students in each grade level class and we have three classes of this type, we multiply to know the number of students:
[tex]3 * 26 = 78[/tex]
Now, if there is an assembly for third grade students, knowing that 4 students were missing, we subtract to know the number of students present:
[tex]78-4 = 74[/tex]
Thus, 74 students will be present at the assembly.
Answer:
74
