Pleasee help Simon, Tessa, and Rick are getting lunch together. They want to order different
things so they can try each others' meals. They narrow down their options to a
hamburger, a hot dog, a chicken sandwich, chicken wings, and vegetarian
nachos.
They order 3 of the meals. Simon does not get chicken. Tessa's meal
has a bun on it. How many different lunch combinations could they have
ordered?
