Grant plans to evaporate enough water from 22 gallons of a 16% ammonia solution to make a 24% ammonia solution. Which equation can he use to find n, the number of gallons of water he should remove? 3.52 (22 minus n) = 0.24 StartFraction 22 minus n Over 3.52 EndFraction = StartFraction 24 Over 100 EndFraction StartFraction 3.52 Over 22 minus n EndFraction = StartFraction 24 Over 100 EndFraction 3.52 + (22 minus n) = 0.24
