"Dad wants one-cent, two-cent, three-cent, five-cent, and ten-cent
stamps.  He said to get four each of two sorts and three each of the
others, but I've forgotten which.  He gave me exactly enough to buy
them; just these dimes."  How many stamps of each type does Dad want?
A dime is worth ten cents.  -- J.A.H. Hunter
