Respuesta :
X = Euro
If we want to find the answer we must understand that 1.20 or 1.2 is equal to 1 Euro. Now, we have completed our first step. And It says that X = Euro (Like I put above.) We know about American dollars that's why we are using a letter to figure it out. So, the expression comes down to 1.2 <<< Which is the number of how much 1$ is in Europe. And X = Euro so It would be 1.2x (If that makes any sense.) Lastly, we would do 1.20 times 25 and we should get our answer of $30.
I hope my very long explanation helped and I hope you understand a bit about expressions now and hope that you do better in the future. Have a nice day!
