Steps:

1) Label data in color (be sure to keep it straight!)

2) Setup a chart to organize the data

3) Take each amount, multiply by the percentage as a decimal for each mixtures.

4) The mixtures are the multiplication of the percentages, but also equal to the sum of the two components mixed into the mixture.

5) You end up with 2 equations & 2 unknowns, whichi is a linear system. You have several options to solve.

6) We solve by substitution., 3x = y

7) We find x = 20 mL, y = 60 mL

8) We confirm using graphing intersection of lines that this is the correct answer.
