Question about party

Sandra • Mon, Dec 08

I just want to make sure I have enough but not too much food. I have 22 people invited to my gender reveal party. I've bought 3 bags of regular meatballs (14 in each bag) and 1 bag of turkey meatballs (I think that's a 24 ct bag) I'm also having baked ziti. Right now I have enough meatballs for 10 sandwiches. How many more bags should I buy?
