He goes to the local Library and looked at the place where some books were sold. He found an economic book for "dummies" at $ 20. Which would be his consumer surplus in the case he buys it?b. As he considered the book at the Library too basic, he explored used books at Internet and found a popular online bookstore that was selling a good textbook at $ 80. What do you think he did? NOTE.
