Homework Help: Math-which is correct

Posted by Christy on Tuesday, September 15, 2009 at 6:22pm.

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 ?

Are you in a country which requires VAT at 16.36%? Or in a state which levies sales taxes on hotel rooms?

this example is just a math story problem. not based on any real life situation.

I think there is a confusion with the budget.
If the budget is US$150, and the conversion is 1€=US$1.20, then the budget is US$150*(1.00€/US$1.20)
=125€
Note how the US$ cancel out to leave &euro as the unit.

I'm sorry -- but it looks like I was wrong in my previous answer.

Please note that it will give you a number in Euros at today's exchange rate -- which is a little different than the one given in your problem. But it should point you in the right direction.
