conversations.value: Find the answer to the math problem: Becky bought 20 apples for 45 cents each and received a $1 discount. Kelly bought 20 apples for 50 cents each and received a 10 percent discount. How much more did Kelly pay than Becky?
conversations.from: assistant
conversations.value: Before the discount, Becky would have paid 20 apples x $0.45/apple = $9
  With the discount, Becky paid $9 - $1 = $8.
  Before the discount Kelly would have paid 20 apples x $0.50/apple = $10
  With a 10 percent discount Kelly paid ($10 x 10)/100 = $1 less
  In total Kelly paid $10 - $1 = $9.
  Kelly paid $9 - $8 = $1 more than Becky.
