(2) Once two factors have been placed on two lines, use these factors to

formulate the equation:

IF

THEN

7

=

X

13

1000

13 X =

7000

X

=

538.46153 ml of 75% elixir

(can be rounded to 538.46 ml)

Then: 1000

ml total volume

-538.46 ml of 75%

461.54 ml of 10%

(3) Because there are only two elixirs involved in this preparation, if one

value is known, the volume of the other ingredient may be found by subtracting the

known volume from the final volume.

Or: The amount of 10% may be found by using the same matrix and by

placing the X opposite the 10% on the matrix: Then the following factors must be used

in the proportion:

=

THEN

X

IF

6

13

1000

cross multiply

13 X

=

6000

X =

461.53846 ml of 10% elixir

(can be rounded to 461.54 ml)
