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?
Answer provided by our tutors
The equation used to find n is:
0.16*22 = 0.24*(22 - n)
0.24*(22 - n) = 0.16*22
5.28 - 0.24n = 3.52
