There are 24 people on the committee and she wants 2 sandwiches per person so that's 24*2 = <<24*2=48>>48 sandwiches
She can buy the croissants by the dozen and she needs 48 croissants so she needs 48/12 = <<48/12=4>>4 dozen croissants
A dozen croissants cost $8.00 and she needs 4 dozens so that will costs 8*4 = $<<8*4=32.00>>32.00
