conversations.value: I need help with this problem:
  Bruce's aunt gave him $71 to spend on clothes at the mall. He bought 5 shirts that cost $5 each and a pair of pants that cost $26. How much money does Bruce have left to buy more clothes?
conversations.from: assistant
conversations.value: Bruce spent 5 * $5 on shirts = $25.
  Including the pants, Bruce spent $25 + $26 = $51.
  Since he began with $71, he has $71 - $51 spent = $20 remaining.
