A saline solution is 20% salt.

How many gallons of water must be added to

dilute the mixture to 8 gals of a 15% saline solution?

here is my method:

using c1V1 = c2V2,

(0.2)(V1) = (0.15)(8)

V1 = 6 gals

So, since 8 gals are required to dilute the saline solution of 15%, 8-6 = 2 gals of water must be added. Is my steps correct ? Hope someone can verify. Thanks
