Since a dozen has 12 eggs, the total number of eggs that Addilynn bought is 6 dozen * 12 eggs / dozen = 72 eggs. If she used half of the eggs, the number of eggs left is 72 eggs / 2 = 36 eggs. While moving the eggs to clean the shelves, she broke 15 eggs, leaving 36 eggs - 15 eggs = 21 eggs. The answer is 21.
