For this case we have that by definition, the distance between two points is given by:
We have to:
Substituting:
ANswer:
<span>Equation:
0.15x + 0.10(5-x) = 0.11*5
---
Multiply thru by 100:
15x + 10*5 - 10x = 11*5
---
5x = 5
x = 1 liter (amt. 15% oj needed)
----
5-x = 4 liters (amt of 10% oj needed)

I graphed it out and it seems that both A and C are correct. I would check them to make sure.
A. X Z Y
B. P N M
C. F E H G D
