Homework Help Forum: 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??? * Math-check my answer - DrBob222, Tuesday, September 15, 2009 at 4:09pm I get a different number. $150 x (1 euro/$1.20) = * Math-check my answer - Christy, Tuesday, September 15, 2009 at 4:25pm Bob are you getting 180 euros ? That was my first answer but it looked wrong * Math-check my answer - DrBob222, Tuesday, September 15, 2009 at 4:28pm No. Are you using a calculator. 150/1.2 = 125. * Math-check my answer - Ms. Sue, Tuesday, September 15, 2009 at 4:30pm 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. $1.20. As DrBob showed, you multiply the number of Euros by the amount you paid in U.S. dollars for each Euro. * Math-check my answer - Christy, Tuesday, September 15, 2009 at 4:43pm So she should only spend 125 euros that would be the equivalent of 150$ 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. Check this site for a computerized answer. http://www.xe.com/ucc/convert.cgi

  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.
