conversations.value: Wally buys bears at the park. A bear is priced at $4.00 for the first bear and a discount of 50 cents per bear is given after that. How much does Wally pay for 101 bears?
conversations.from: assistant
conversations.value: If the price of an additional bear drops by fifty after the first purchase, the price of each additional bear is $4.00 - $0.50 = $3.50
  Since Wally bought 101 bears, he was charged fifty cents less on 101-1 = 100 bears.
  The total cost for the 100 bears is 100*$3.50 = $350
  For the 101 bears, Wally paid a total of $350+$4 = $354
