We did part (b) and (c) just to “match the answer”, and (a) is just toooooo difficult to figure out, unless we treat all as packs of 12????
But why??


Or is that something really "creative" like this, so a mix and match of tiles to form the odd looking shape??

Looks a screwed question answer. The small packs is 7=3.5*2. The other pack numbers are too small with 6 tiles per pack, but the numbers make sense with 12 tiles per pack throughout. However, then medium would cost less than small. Screwed.
