I was wondering if anyone here could tell me how to form questions properly using the expression "tener" + "que" + infinitive.
I would like to learn how to say such a question as: "Why does Sergio and I have to go to the store?
My guess is: ¿Por qué tenemos Sergio y yo que ir a la tienda? but that doesn't sound quite right. Is the only option here something like: ¿Por qué tenemos que ir Sergio y yo?
¡Gracias por la ayuda!
