Two dozen bandages would be 2 * 12 = 24 bandages.
If the box had 8 less than two dozen bandages, then it had 24 - 8 = 16 bandages.
Peggy used two bandages on her left knee and three bandages on her right knee, so she used a total of 2 + 3 = 5 bandages.
If there were 16 bandages in the box and Peggy used 5 bandages, then there were 16 - 5 = 11 bandages left in the box.
