Roman mixes 12 liters of 8% acid solution with a 20% acid solution, which results in a 16% acid solution. Find the number of liters of 20% acid solution in the new mixture. Construct a table to organize the information, and show all of your work to solve the problem.

Solution | Liters of Solutions | Percent of Acid | Liters of Acid
8% solution | | |
16% solution | | |
20% solution | | |

Respuesta :

Let n be the amount of 20% solution. Then:
.08(12)+.2n=.16(12+n)
.96+.2n=1.92+.16n
.04n=0.96
n=24 liters of 20% solution in the new mix
