Spanish language Q&A Forum

Hello!  I thought the hint for "to sign up for" was "inscribirse a."  The correct response was "inscribirse en."  Are both forms acceptable?  Thank you!

This is one of the nuances of usted that I still haven't quite figured out. At my retail job, I often assist Spanish-speaking customers. However, I am not sure if these situations warrant using more formal language. In English, I address my customers politely with "Sir" or "Ma'am" but the language I use otherwise as I'm assisting them is more informal. I want to maintain the same tone of politeness yet casualness in Spanish as English but I don't know if it comes across as too formal. For context, I am in my early twenties and the customers I've spoken to are almost always older than me ranging from their thirties to more elderly people. Obviously, for my older customers, I would use usted but would it be necessary to use usted for people who are not that much older than me? I don't know if there is anybody here who can shed some light on this topic. In Spanish-speaking countries do retail employees typically address their customers with more formal, usted language?

Thank You

"we were studing at the university of Salamanca during the 90'

While translating the verb study in spanish , I think we will use preterite indefinido (pretertio perfecto simple) because of time frame (during the 90) instead of preterite imperfecto. 

Please guide me on this. 

Hola, tengos dudas en la acentuación de las palabras arriba. Según lo que he estudiado "compráoslos" no sería correcto. La tilde debería ser en o: "cómpraoslos".

También en otras palabras tengo dudas de la accentuación.

No estoy segura. ¿Si esto (lo que esta escrito en los ejercicios)es correcto por favor digame cómo?
