Charlie and Freddie send their exquisite casting, which consists of 30 pieces, laundry. Freddie explains that as his bundo contains half of the fists and a third of the shirt necks, 27 cents should cost, since 4 shirt fists are worth the same as five necks. Hop Lee, who is not very shower in mathematics, wants to know How much must charge Charlie for the other Phardo.

If there were 30 pieces of clothes and Freddie was charged 27 cents for half of the fists and one third of the shirt necks, there were 12 fists and 18 necks, so Charlie should 39 cents, since the necks are worth 2 cents and the fists 2 and a half.
