Faith mixes 14 liters of 12% acid solution with a 30% acid solution, which results in an 18% acid solution.

Let x represent the number of liters of 30% acid solution used, and let y represent the number of liters of mixture. Which system of equations can be used to find the number of liters of 30% acid solution in the mixture?

a. y=x + 14; 0.18y = 0.3x + 1.68

b. y=x + 14; 0.12y = 0.3x + 1.68

c. y=x + 14; 0.12y = 0.3x + 4.2

d. y=x + 14; 0.18y = 0.3x + 4.2
