A laboratory technician needs to make a 27-liter batch of a 40% acid solution. How can the laboratory technician combine a batch of an acid solution that is pure acid with another that is 10% to get the desired concentration?

M = 27 liters

u = volume of 10% acid. unknown.

v = volume of 100% acid. unknown.

L = 40%

H = 100%

T = target concentration of acid, 40%
