I still get confused with These/Those and this/that, can someone pls give a simple example of when to use them?
I remember them this way: "this and these both have t's" ie: esta, esto/ estas, estos (this/these). If there is no "t", then it's "those"; ie: eso/esa, esos/esas. Hope this helps.
why cost and not costs?
"costs" is only used when the subject is third person singular (e.g. This ticket costs thirty pesos).
For any other subject, you use "cost".
$1.59! Para qué son?
¿Un corto viaje en autobús?
Is there a difference between entradas and boletos?
