Hey there!
The answer is es and están. It’s es because it is a characteristic. It’s son because it’s plural, and aburridos meanest it’s a characteristic. La película es muy aburrida y mis amigos están aburridos de verla.
I hope this helps!
First ¿Cuánto Cuesta? means How much in Spanish to answer correctly to that answer you say a number for an example:
Girl : ¿Cuánto Cuesta?
Guy: Tres
you may saw the object you are talking about.
But if you wan to answer as saying in terms like how much you love someone you say todo esto which means this much.
Please give me the question. I’ll reply in the comments
