Answer:
The two 50ml bottles
Step-by-step explanation:
(I will be using the $ but just change the sign to the euros)
$55/80ml= .68 per ml
45+22.5= $67.5
67.5/100 is about $.67
Therefor the two 50ml bottles is cheaper per ML and you get more product

1. A
Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution. This is called an "inconsistent" system of equations, and it has no solution.

2. C
That's right. If a system of equations has a solution, then their graphs intersect, and the point where they intersect is the solution because it's the point that satisfies each equation in the system.
Straight-line graphs with the same slope are parallel lines, and they never intersect, which is another way of saying they have no solution.
