You can put this solution on YOUR website! A chemist has a 30% acid solution and a 50% acid solution. How many liters of each solution does the chemist need to make 100 liters of a 38% acid solution.
***
let x=amount of 30% solution needed
100-x=amount of 50% solution needed
..
30%x+50%(100-x)=38%*100
.30x+50-.50x=38
.20x=12
x=60
100-x=40
amount of 30% solution needed=60 liters
amount of 50% solution needed=40 liters
