x = number of comics Ross bought
A = 10*x = amount spent on buying those x number of comics at $10 each
B = 17*(x-1) = amount Ross gets from selling every comic book except one
B-A = 17*(x-1)-10x = 7x-17 = profit = 49
7x-17 = 49
7x = 49+17
7x = 66
x = 66/7
x = 9.42857 approximately
Because x isn't a whole number, I'm thinking that there's a typo in the problem somewhere. I would double check with your teacher.

Answer:
Option A is correct
An equation does not have an solution of 1/4 form.
Explanation:
To determine which equation does not have a solution of 1/4 for n.
Option A:
Substitute the value of n = 1/4 we have;
False
Similarly for,
Option B :
Substitute the value of n = 1/4 we have;
True
Option C:
Substitute the value of n = 1/4 we have;
True
Option D:
Substitute the value of n = 1/4 we have;
True
Therefore, an equation does not have an solution of 1/4 form.
