Madison purchased a three-year-old computer from kami for $300. kami told her the price seemed fair but she really had no idea what it was worth and just wanted to get rid of it. madison, who knew little about computers, thought she had a great deal. after madison returned home, she discovered from a computer expert friend of hers that the computer was not worth as much as she believed. madison wanted to return the computer claiming that they were both mistaken about value, but kami said, "no way!" who should win in the dispute between madison and kami and why?
