conversations.value: Candice put 80 post-it notes in her purse before she headed out to her job at the coffee shop.  On her way, she stopped off at the store and purchased a package of Post-it notes;  At work, she placed a single Post-it note on each of 220 different cups of coffee.  If she had 23 post-it notes remaining overall, how many Post-it notes were in the package that she purchased?
  Give me a solution to this problem
conversations.from: assistant
conversations.value: Let's let x be the number of post-it notes in the package that Candice purchased.
  Then, the total number of post-it notes she had when she left the store was 80+x.
  And if she used 220 Post-it notes at work and had 23 left, then 80+x=220+23
  Subtracting 80 from each side of the equation, we see that x=220+23-80=163 Post-it notes.
