Question 16754
Well in my first attempt, I tried to get the largest number of large boxes that would not give more cookies than required, which is 3 large boxes.  However, this did not seem to be working out, so I dropped down to 2 large boxes, which would be 4 oatmeal, 4 choc chip, 6 shortbread.  


This leaves a need for 11 oatmeal, 6 choc chip, 5 shortbread.  


For this, you can order 5 medium boxes, providing 10 oatmeal, 5 choc chip, 5 shortbread.  You still need 1 oatmeal, 1 choc chip, which is exactly 1 small box.


In summary, you should order 2 large, 5 medium, and 1 small box.
