.
Let x = ounces of water evaporated
then
.10(90) = .15(90-x)
9 = 13.5 - .15x
9 + .15x = 13.5
.15x = 4.5
x = 4.5/.15
x = 30 ounces
You can put this solution on YOUR website! Let = ounces of water to evaporate
given:
salt in 10% salt solution:
In words
(ounces of salt in 10% solution)/(ounces of final solution) = 15% ounces
30 ounces of water must be evaporated
check answer:
Removing 30 ounces of water from the ounces
of water leaves ounces of water
OK
