The salt water content of salt water is 5% (based on its weight).
How many pounds of tap water should be mixed with 30 kg of sea water so that the result contains 3% salt.
:
let x = amt of water required to accomplish this
A typical mixture equation, percent in the decimal form
.05(30) = .03(x+30)
1.5 = .03x + .9
1.5 - .9 = .03x
.6 = .03x
x = .6/.03
x = 20 kg of tap water required
