Question

At mcdonalds you can order mcnuggets in boxes 6,9, or 20. by ordering 2 boxes of 6 you can get twelve. butyou cant get 13, since no combination of 6,9, and 20 adds up to 13. what is the greatest number of mcnuggets that you cant order?

Answer 1

That would be 19. I belive this bc 9 plus 9 is 19 and no matter what combination of boxes you will not have 19 chiken nugets
