check my answer please.....
1 euro is worth 1.2 U.S dollars
if I budget 150$ per night for a hotel room. What is the maximum number of euros I should spend for a room?
My answer is 108 euros as a maximum (with an actual number of 107.425)
Correct???

I get a different number.
$150 x (1 euro/$1.20) = 
Bob are you getting 180 euros ?
That was my first answer but it looked wrong 
No. Are you using a calculator. 150/1.2 = 125.

Yes, Christy, $180 is correct.
Think of it this way. If you buy a cup of coffee for 1 Euro, you're spending U.S. $1.20. As DrBob showed, you multiply the number of Euros by the amount you paid in U.S. dollars for each Euro. 
So she should only spend 125 euros that would be the equivalent of 150$ US ?
I am confused as to what the true answer should be ?
