Answer 1

Yes, the word '700' (seven hundred) is a noun, a word for a thing.

All numbers are nouns that can function as the subject of a sentence or a clause, and as the object of a verb or a preposition.

You still owe me 700 dollars. (adjective, describes the noun dollars)

I can stop by my bank in the morning for the seven hundred. (noun, object of the preposition 'for')

I'll bring the 700 by your house after I go to the bank. (noun, direct object of the verb 'bring')
