subjects is 84. What is the lowest grade?

84*(N-1) + G = 82*N
Where N is the number of grades and G is the lowest grade.
You have one equation with two variables. Need another equation to solve it.

The average is total / amount of grades or:
A+X/N+1=82
If we take out the lowest is
A/N=84
So X the lowest grade is X=82-2N
So if the grades were 10 X is X=82-2*9 ; X=64

The lowest grade depends on the number of the subjects.

There is not enough information to solve the problem. We would need to know how many subjects were used in finding the averages.

Assuming that we are grading on a curve, we also don't count the highest score either. However i figure that the low grade would probably be 80 or less.

You can only arerive at a definitive answer if you know the number of subjects taken.

i think we need to know how many assignments were graded to be able to figure this out

Depends on how many subjects...
