three subjects meme

So how this is supposed to work is reply here and I'll give you 3 subjects I don't think you know or care much about. Then you talk about those subjects in your journal. It's interesting to see who knows what about what. I am not sure I am up to the giving of topics, but I was curious what zhelana would ask me to talk about:
( hippos, magic, drumming )

and from stultiloquentia:
( walruses, blimps, cuneiform )

1) Between "Gigantitan", Heroes' Day, "Papa-Garou", "Miraculer", and whatever else it's reasonable to suppose happened offscreen: how many hours has August been Ladybug and Chat Noir's responsibility, not his mother's? (This comic by adobsonartworks is absolutely the correct visual.)

2) How much would August's mother expect to pay a babysitter for August? How much does Nadja Chamack pay Marinette to babysit Manon?

3) In order to give everyone at the local fire house a delicious treat from the boulangerie-pâtisserie (assuming everyone at the fire house can eat something from the boulangerie, anyway, which I know is not a safe assumption), how big a purchase are we talking? In terms of all of (a) how many items purchased, (b) what size vehicle is necessary to get the whole purchase to the fire house, and (c) euros spent.

4) How much cash is it reasonable to suppose Lila Rossi ordinarily carries?

5) If (4) is smaller than (3c), then what do (3a) and (3b) become if we set (3c) equal to (4)?
