Jack works in a bookstore. Here is a note from his boss, Ben. Jack will decide what books to order（订购） according to the notes and the information about the books.

Hi Jack,

You must hand in the order list of books by the first working day of every month. The rules for choosing books are：

For textbooks：

※ August is coming. We must have all textbooks, without thinking of other rules.

For books which are not textbooks：

※ If more than 5 copies were sold last month, we choose them. But if there are 5 or more in stock(现货)，we do not make an order.

※ If the wholesale(批发) prices are higher than ﹩75, we don't choose them. And we don't order anything whose retail(零售) price is higher than ﹩100.
