Answer:
I like the country Mexico because it is big and I like to buy the snacks. The snacks cost 100 pesos (5 U.S dollars). I also like to travel to Panama. In Panama, I always buy a lot of clothes. I pay 20 balboas for a pullover in Panama. When I travel to Nicaragua, I buy a wallet. A wallet in Nicaragua costs thirty córdobas.
Different countries have different currencies so I don't know how much it would be in the U.S. I have been to Mexico so I know that 100 pesos over there is 5 dollars here. Hope this helps. :)
Either way is correct.
but in mexico it usually goes before and in spain it's usually attached to the end.
