A store selling used books paid $195 for a collection of old books. The store sold the entire collection and made a profit of $127.50 or abotu 50 cents a book. How many books were in the collection?
How many books were in the collection?
The previous answer assumes that books were sold for $0.50 each. The way I read it, they made $0.50 profit per book, which suggests there are
127.50/0.50 = 255 books,
in which case the $195 is a red herring. Not the most clearly worded problem...
Reply:$195 cost of books
+$127.50 profit
=$322.50/$0.50
= 323 books
