Question 749208: This is a word problem. Solution A is 8% and Solution B is 4%. If a technician wans to mix them to make 150 liters of Solution C which is 6% acid, how many liters of each should be mixed together! I REALLY need help! Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! This is a word problem. Solution A is 8% and Solution B is 4%. If a technician wans to mix them to make 150 liters of Solution C which is 6% acid, how many liters of each should be mixed together!
---------
Equation:
acid + acid = acid
0.08x + 0.04(150-x) = 0.06*150
------
8x + 4*150 - 4x = 6*150
----
4x = 2*150
x = 75 liters (amt. of 8% solution needed)
150-x = 75 liters (amt. of 4% solution needed)
