Respuesta :

wouldn't the answer be 10 euros
$.90x10 = $9
1x10 = 10
[tex] \frac{.9}{1} = \frac{9}{x} [/tex]    Solve for x.

.9x=9*1    Divide both sides by .9

x=[tex] \frac{9}{.9} [/tex]=10

You would get 10.00 euros.

You can also think of it in this way, that you just move the decimal point over one to the left to get 10.
