Question 1147449
Actually, there's a lot a variation in the %age of salts in solution.
There's no reason to assume it's in NaCl in water.
=====================================
A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is 35% salt and Solution B is 85%  salt. She wants to obtain 130 ounces of a mixture that is 80% salt. How many ounces of each solution should she use?
----------------------
A = amount of 35%
B = amount of 85%
----
A + B = 130 --- total solution
35A + 85B = 130*80 ---- total salt
---
Can you do the rest?
==========================
IDK if there is any salt that can be dissolved in any solvent at 85%.
I don't know why anyone would be angered by the question, tho.
