Answer:

!2 bottles

Step-by-step explanation:

Given

[tex]8\ bottles = 13\ litre \\[/tex]

Required:

Number of bottles for 18.5 liters

Represent this with x.

So:

[tex]8\ bottles = 13\ litre[/tex]

[tex]x = 18.5\ litre[/tex]

Cross Multiply

[tex]x * 13 = 8\ bottles * 18.5[/tex]

[tex]x * 13 = 148\ bottles[/tex]

[tex]x = \frac{148}{13}\ bottles[/tex]

[tex]x = 11.4\ bottles[/tex]

Hence, she needs 12 bottles
