Question:
A chemist needs 2 liters of a 26% acid solution. He has an 18% solution and a 50% solution available to form the mixture. How much of each should be used to form the 26% solution?

Solution:

Given solutions at 18% and 50%, need 2L of 26%.
Ratio of 18%:50% = (50-26):(26-18) = 24:8 = 3:1 so 1.5L of 18% + 0.5L of 50%

x, volume of the 18%
2-x, volume of the 50%

Let = liters of the 18% mixture needed
Let = liters of the 50% mixture needed

Multiply both sides of (1) by and
subtract (1) from (2)
