Michelle is bringing sandwiches to work to give to her co-workers. She gives 4 sandwiches to one of her co-workers and keeps twice this amount for herself. If she had originally made 20 sandwiches, how many sandwiches does she have left to give to her other co-workers?
Michelle kept 4 sandwiches * 2 = <<4*2=8>>8 sandwiches for herself.
This leaves 20 total sandwiches – 4 sandwiches for a coworker – 8 sandwiches for herself = <<20-4-8=8>>8 sandwiches for her other co-workers.
