Answer:
Add all of the items, then multiply by 5
Step-by-step explanation:
Why by 5? Well, in order to make 
5 cookies per player one batch would be made
so, 10 cookies pp = 2 batches
15 cookies pp = 3 batches
20 cookies pp = 4 batches
 and then you would need 4 more to make 2 dozen, so you would then make another batch and have a few extra, but you would have 2 dozen per player!
hope this helps!!
