Faith mixes 14 liters of 12% acid solution with a 30% acid solution which results in an 18% acid solution.
If x represents the number of liters of 30% acid solution used, which equation can be used to find the number of liters of 30% acid solution in the mixture?
.30x+.12(14)=.18(14+x)
.30x+1.68=2.52+.18x
.30x-.18x=2.52-1.68
.12x=.84
x=7
ans: the number of liters of 30% acid solution used in the mixture is 7
