Final answer:
The correct verb form to complete the sentence is 'compramos'
Step-by-step explanation:
The correct verb form to complete the sentence is compramos. The sentence would then be: Ana y yo compramos zapatos en nuestra tienda.
In this sentence, the subject is the pronoun 'Ana y yo,' which means 'Ana and I.' Since the subject is first person (I), the correct verb form is the first person plural form 'compramos,' which means 'we buy' in English.
For example: Ana y yo compramos zapatos ayer. (Ana and I bought shoes yesterday.)
