Answer 1

It’s 3 because I don’t know but I’m just kinda confused tho

Answer 2

The party was 4 hours long.

Explanation:

Subtract the total by the amount already known was spent directly.

320.91-200.39= 120.52

Now, in order to figure out how many hours the part was, take how much each hour and divide it by the remainder of money.

Thus, 120.52/30.13 = 4

All things put into consideration, The party was 4 hours long.

I hope this helped!!
