Joyce has 42 liters of 40% saline solution in a container and plans to add a certain amount of a 10% solution to weaken the saline concentration to 24%. How many liters of the 10% solution should she add?
**
let x=amt of 10% solution to add
42+x=amt of final 24% solution
..
40%*42+10%x=24%(42+x)
16.8+.1x=10.08+.24x
.14x=6.72
x=6.72/.14
x=48
amt of 10% solution to add=48 liters
