Question 749223: Solution A is 12% acid and Solution B is 4% acid. If a technician wants to mi them to make 60 liters of Solution C which is 10% acid, how many liters of each should be mixed together? Answer by josgarithmetic(39620) (Show Source):
You can put this solution on YOUR website! {amount of acid from A plus amount of acid from B}/{volume of solution C} = {concentration of solution C}
H = 12%, for solution A
L = 4%, for solution B
T = 10 %, wanted as solution C
M = 60 liters solution C
u = volume to use solution A
v = volume to use solution B
Solve the system for u and v, and then substitute the known values to compute u and v.
