A chemist needs 160 milliliters of 49% solution but has only 29% and 93% solutions available. Find how many milliliters of each that should be mixed to get the desired solution.
***
let x=amt of 29% solution to mix
160-x=amt of 93% solution to mix
..
29%x+93%(160-x)=49%*160
.29x+148.8-.93x=78.4
.64x=70.4
x=110
160-x=50
amt of 29% solution to mix=110 mm
amt of 93% solution to mix=50 mm
