Erin bought a box of stickers that looked like little white doughnuts to reinforce the pages in her notebook. There were two thousand, nine hundred fifty stickers in the box, but she could not use some of them. One-fifth of them were stuck so tightly together that she could not detach them from each other. Thirty-three of them had no holes in the center. One-tenth of them had no glue. How many were left that she could use?

Total number of stickers

          = 2,950

  Number of stickers stuck

    = 1/5 of 2,950 = 590

  Number of stickers with no holes

     = 33

  Number of stickers with no glue

      = 1/10 of 2,950 = 295

Number of stickers that could be used

  = 2,950 - (590 + 33 + 295)
  = 2,950 - 918 = 2,032
