Your family is traveling to Mexico on vacation. You have saved $500 to use for spending money. If 269 Mexican pesos is equivalent to 25 United states dollars, how much money will you get when you exchange your $500 for pesos?

OpenStudy (anonymous):

Is 5380 a choice?

OpenStudy (anonymous):

It's not multiple choice

OpenStudy (anonymous):

I think I have to cross multiply, right?

OpenStudy (anonymous):

You would solve this with a proportion.

OpenStudy (anonymous):

So yes, you would cross multiply.

OpenStudy (anonymous):

Do you know how to set it up?

OpenStudy (anonymous):

Would it be $500 over x equal to 25 over 269?

OpenStudy (anonymous):

Yes it would

OpenStudy (anonymous):

So you cross multiply to solve for x

OpenStudy (anonymous):

So I would cross multiply 500 and 269, which equals 134,500, then take that and divide that by 25, which would give me 5,380. Would that be x?

OpenStudy (anonymous):

That is correct!

OpenStudy (anonymous):

Thanks for helping me through that? Mind helping me through one more?

OpenStudy (anonymous):

I said the answer first, so techncally, I deserve a medal. xD

OpenStudy (anonymous):

@AnswerMyQuestions, you didn't really help me through it. Although I will give you both a medal

OpenStudy (anonymous):

I can help you through one more.

OpenStudy (anonymous):

And you can't give 2 people a medal.

OpenStudy (anonymous):

You can give it to @idiotdancer :)

OpenStudy (anonymous):

I can help with more if you'd like.
