How long in business?

How long in business?
 

Hi

Can someone tell me which one is correct if I want to ask someone how long they have had their business?

Cuantos anos tienes en la negocio

Cuanto tiempo tienes en la negocio

Perhaps niether are right!

Thanks

Jon

Both of the phrases you proposed work, with the changes I marked in red, but you may want to use the verb llevar instead of tener. That is the more common way to ask the question.

There is an 'Accents' drop-down menu just above where you type. You can use it to insert all the special characters you need while typing Spanish. Your first question, without the use of the letter ñ, turns out to be rather comical. ;)
