1. 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.

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.

Equation:
acid + acid = acid
0.08*12 + 0.20x = 0.16(12+x)


8*12 + 20x = 16*12 + 16x
4x = 8*12
x = 24 Liters (amt. of 20% solution needed)

The answer is $9.90 with rounding to the nearest tenth
