My wife recently purchased two books from her local bookshop. She showed me the receipt, which showed the cost of each book and the three-figure total cost. I noticed that all of the digits from 1 to 9 had been printed. Coincidentally, exactly the same happened to me when buying two different books, but my more expensive book cost more than hers. In fact, it would not have been possible for that book to have cost more.
How much did I pay for the more expensive book?
