Homework Statement



A pharmacist is mixing an 2.3% saline solution and an 9.6% saline solution to get 2.6 litres of a 5% solution. How much of the 2.3% solution is needed?



Homework Equations


Amount = Rate x Total


The Attempt at a Solution



I have no idea how to set this up.

Would I do something like .023x + .096y = .05(2.6) then solve for x and y?



I am not sure where to go with this. Any help with be greatly appreciated.
