There are 30 dozen in a case, and 15 dozen in a box.
A dozen
12
Eggs are not sold by the box, but the dozen and in California I am paying 4.99 a dozen.
240
A box with 144 pencils in. A gross refers to a group of 144 items (a dozen dozen or a square dozen).
So that the steam from the bun can be out from the box
A mole is just a number, like a dozen, but a lot bigger. So the question is like asking "Does a box of a dozen small eggs have the same number of eggs as a box of a dozen jumbo eggs?" (Yes, they both have a dozen, 12, eggs. They both have Avogadro's number of molecules.) Trick question: a mole is a count of molecules, not atoms. A mole of water would have half again as many ATOMs as a mole of oxygen, since water comes 3 atoms to the molecule, but oxygen as O2 has 2 atoms per molecule. Similarly a dozen breakfasts of 3-egg omelets would have half again as many eggs as a dozen breakfasts of 2 fried eggs.

You can purchase freshly made buns at a lot of places. You can buy them at big box stores like Walmart or Costco. You can buy them at grocery stores that have a bakery section. You can also buy them from a local bakery.
It is thirteen because the bakers often used to always make a spare so when preparing sets of cakes, buns, bread in dozens, if one went wrong it would not waste time etc. because there would always be a spare.
