For a long time, the fast-food chain McDonald's sold its Chicken McNuggets in packs of 6, 9, and 20. If one wants some number of these nuggets, how many of each pack would one have to buy? Are there any numbers of nuggets that one cannot get in this fashion?
Variations:
A McDonald's Happy Meal includes a pack of 4. What are possible numbers from 4, 6, 9, and 20?
McDonald's now sells Chicken McNuggets in sizes of 4, 6, 10, and 20. What numbers of pairs of nuggets are possible?
If one can remove packs of nuggets in addition to adding them, what numbers are possible?
There are similar puzzles involving coins and bills (banknotes).
How many pence (pennies) can one make with the British two pence and five pence coins?
Most currency is decimal, and uses multiples like 1, 2, 5, 10, 20, 50, 100, ... so one can compose the same problem with (say) US $20 and $50 bills.
The US is a bit unusual about less than $1 value. Its coins are a penny (1c), nickel (5c), dime (10c), quarter (25c), and a half-dollar (50c).
So one can ask how many multiples of 5c can one make with dimes and quarters.
