How much water must be evaporated from 100 pounds of a 4% brine to get a 5% brine?

The idea with ANY mixture problem is to find something constant.abhinavadi said:
4% Brine - Water = 5% Brine
What doesn't change? The salt.
W = Pounds of Water to Evaporate
4%*100 lbs - 0%*W = 5%*(100 lbs - W)
Or, you can play with the water, instead.
96%*100 lbs - 100%*W = 95%*(100 lbs - W)
Solve whichever you wish, but usually, the one with the "0%" is easier.
