Hacemos una regla de 3 simple:
100% _______> 18 €
108% _______> x €
[tex]x \: = \: \frac{18 \: \times \: 108}{100} [/tex]
[tex]x \: = \: \frac{9 \: \times \: 108}{50} [/tex]
[tex]x \: = \: \frac{9 \: \times \: 24}{25} [/tex]
[tex]x \: = \: \frac{486}{25} [/tex]
[tex] \boxed{ \bold{x \: = \: 19.44 €}}[/tex]
