conversations.value: I need a clearer understanding of how to solve: Lyssa and Precious took an English proficiency exam. Lyssa answered 20% of the items incorrectly. Precious got 12 mistakes. How many more correct answers did Lyssa get than precious if there were 75 items in the exam?
conversations.from: assistant
conversations.value: Lyssa got 75 x 20/100 = 15 mistakes.
  Lyssa's score is 75 - 15 = 60.
  The score of Precious is 75 - 12 = 63.
  Thus, Lyssa got 63 - 60 = 3 more correct answers than Precious.
