Remember the triangular inequality says that if u and v are vectors then
Since the magnitude always is a nonnegative number and the magnitude of u is 5 units and the magnitude of v is 4 units ,
Then possibles values for the magnitude of u +v are in the interval
If 
of students were juniors and seniors that leaves the 36 sophomores to be 
or 
of attendees. I got by converting 
and adding it to 
.
Now if 36 is of the equation that means theirs at least 36 juniors and seniors.
Lets start with seniors. there should be just over 36 of them there. Lets start by multiplying 36 by to figure out how many 
is.
The equation would look like this 36*(3/12)
start with 3/12. this equals .25 or.
Now multiply 36 by .25. this equals 9.
We have 9 students per of the attendees.
To get the amount of seniors add 9 to 36
because we already stated is 36.
36+9=45
Now to find the juniors add another 9 to create.
45+9=54
In total you have:
36 sophomores
54 juniors
45 seniors
