Answer 2

0.91 Euros

Explanation:

We know that 11 U.S. Dollars can be exchanged for 10 Euros. We know that exists a linear relationship between the amount of U.S Dollars and the amount of Euros. This linear relationship can be written as :

`(11(U.S.Dollars))/(10(Euros))=(1(U.S.Dollars))/(x)`

If we solve the equation for x :

`x=(1(U.S.Dollars).10(Euros))/(11(U.S.Dollars))=(10)/(11)(Euros)`

`x=0.9090(Euros)` ≅ 0.91 Euros

We find that for 1 U.S.Dollar I will receive 0.91 Euros.
