How much was spent for a certian amount of a fabric?

(1) The cost of the fabric was $15 per square yard.

(2) An additional 6 square yards of fabric would have cost an additional $90.

St1:
Insufficient. We do not know how many square yards was purchased.

St2:
Currently -> x square yards = y$
x+6 square yards = $(y+90)

Insufficient. We do not know how much x square yards cost.

Using St1 and St2:

1 square yard = $15
x square yards = $15x
(x+6 square yards) = $15x + 90

Now we still do not know how many square yards was purchased. Insufficient.

x+6 square yards) = $15x + 90
could we not find the value of x from this and multiply by 15 to give the total cost? I am confused why the answer is E and not C. Can somebody please explain

Because this is not a valid equation:

x+6 (square yards) = $15x + 90

You are equating Square-Yards with $

The answer is E i get it .

But if 1 and 2 actually yeild an answer assumming linearity of cost ---is the assumption acceptable in GMAT

This is the first easy question I saw on gmatclub.
It is E:
St 1 and st 2 give us the same information: each square yard of fabric cost 15 dollars, however, they don’t provide us with information regarding the the number of square yards.
