Sticky Note
A college student bought 11 books for fall classes. If the cost of his anatomy textbook was three times the mean cost of the other 10 books, then the cost of the anatomy textbook was what fraction of the total amount he paid for the 11 books?
  1. 2/3
  2. 3/10
  3. 3/11
  4. 3/13
Explanation

Because you aren't given the cost of any book, you can plug in your own values.

Let's say that the average cost of the textbooks, excluding the anatomy textbook, is $10.

You can make all the books cost $10 each to make the problem easier.

The anatomy textbook would cost $30.

The total cost of all the textbooks would be $130.

The anatomy textbook would be $30/$130=3/13
