conversations.value: Can you break down the solution for me for this math problem: James is running a fundraiser selling candy bars.  Each box has 10 candy bars in it.  He sells 5 boxes.  He sells each candy bar for $1.50 and buys each bar for $1. How much profit does he make from these sales?
conversations.from: assistant
conversations.value: He makes 1.5-1=$.5 from each candy bar
  He sells 5*10=50 candy bars
  So he makes 50*.5=$25
