Betsy is sewing a quilt.  The quilt is made up of 16 squares sewn together on one side and 16 squares sewn together on the other side.  Betsy has already sewn 25% of the quilt together.  How many more squares does she need to sew together?
The quilt is made of 16 squares on one side and 16 on the other so 16+16 = <<16+16=32>>32 squares total
She has already sewn 25% of the quilt so she has sown together .25*32 = <<25*.01*32=8>>8 squares
Betsy still has 32-8 = <<32-8=24>>24 more squares to sew together
