A pool has 48 blue tiles and 32 red tiles. If the pool needs 100 tiles to be completed, how many more tiles are needed?
How many tiles does the pool currently have? ** The pool currently has 48+32 = <<48+32=80>>80 tiles.
How many more tiles are needed? ** The pool needs 100-80 = <<100-80=20>>20 more tiles to be completed.
