Math Help Please
The concentration, C, of salt in a solution is determined by the formula C=(A)/(s+w), where A= constant amount of salt, s=initial amount of solution, w is the amount of water added. How much water must be added to a 1L bottle of 30% salt solution to get a 10% solution? How much water must be added to a half-litre bottle of 10% salt solution to get 2% solution?

Now I have that image in my mind and can't continue to solve the problem.

This is not science. This is about radical expressions
@HolyDragon ok. That helped me a bit thanks.
Note, this is guess work.
C=A/(s+w)
C(s+w) = A
A is a constant
C(s+w) = C(s+w) since A is constant
3/10 (1 + (0))= 1/10 (1 + w)
Then you solve for w to know how much is added.
