Approximately 219 Liters.
My math:
0.5 = (81 + 0.1 x) / (9 + 0.9 x)
0.5 (9 + 0.9 x) = (81 + 0.1 x) / (9 + 0.9 x) * (9 + 0.9 x)
4.5 + 0.45x = 81 + 0.1 x
4.5 + 0.45 x - 4.5 = 81 + 0.1 x -4.5
0.45 x = 76.5 + 0.1 x
0.45 x - 0.1 x = 76.5 + 0.1 x - 0.1 x
0.35 x = 76.5
0.35 x / 0.35 = 76.5 / 0.35
x = 218.57143

mary mixed 2l of an 80% acid solution with 6l of a 20% acid solution. what was the percent of acid in the resulting mixture
A pharmacist mixed a 20 percent solution with a 30 percent solution to obtain 100 liters of a 24 percent solution. How much of the 20 percent solution did the pharmacist use in the mixture (in liters).
Mixing 80 liters of 15% solution and 520 liters of 90% solution will give 600 liters of 80% solution.

Let L be the liters to be added. Then (L) x (0.2) + (40 x 0.9) = (L + 40) x 0.6 0.2L + 36 = 0.6L + 24 36 - 24 = (0.6 - 0.2)L 12 = 0.4L L = 12/0.4 = 120/4 = 30 Liters
80 liters
