Carlon plans to evaporate a number of gallons of water from 90 gallons of a 15% salt solution to make a 25% salt solution. Which equation can he use to find x, the number of gallons that should be evaporated?

Original
(Gallons)
Removed
(Gallons)
New
(Gallons)
Amount of Salt
13.5
0

Amount of Solution
90
x

StartFraction 13.5 Over 90 minus x EndFraction = StartFraction 25 Over 100 EndFraction
StartFraction 13.5 Over x EndFraction = StartFraction 25 Over 100 EndFraction
13.5 (90 minus x) = 0.25
13.5 (90 minus x) = 25
