Question

It's Saturday night, and you are at your friend Roberto's

birthday party. Roberto introduces you to his
grandmother. How should you greet her?

Answer 1

Buenos noches come estas usted

Answer 2

Buenas noches! Como esta usted?

Step-by-step explanation:

Translation: Good evening! How are you?

Como esta usted is the formal way of saying how are you because she is an elder and you should not speak to her how you speak to your friends. Good evening is also more formal than saying hello.
