Answer 2

Answer:

23.3%  (approx)

Step-by-step explanation:

The final solution is 1 litre.  As 60% of this is vinegar, the volume of vinegar is 60% of 1 litre = 600 ml.

The volume of vinegar in the first dressing was 90% of 550 ml = 0.9 × 550 ml = 495 ml.

So the volume of vinegar in the second dressing was 600 ml - 495 ml = 105 ml.  The volume of the dressing used was 450 ml.  So as a percentage, the amount of that dressing that was vinegar is:

( 105 / 450 ) × 100%  =  (70/3)%  ≈ 23.3% (approx)
