'The Cookie Crunchers' Among Bakers

Cassie, Jon, Luke, Maria, and Sahas baked a batch of 36 cookies, two-thirds of which were chocolate chip. The rest were plain. They each ate at least one right away. The cookies were so delicious, only one-and-a-half dozen are left, of which half are plain.

1. Cassie is allergic to chocolate.
2. Luke ate twice as many chocolate chip cookies as plain cookies.
3. Sahas and Maria each ate as many cookies as Luke and Cassie combined.
4. Sahas ate more chocolate chip cookies than Maria.

If all the cookies were eaten by the bakers themselves, how many cookies of each kind did each person eat?
