conversations.value: A hot dog stand sells 10 hot dogs every hour, each one selling for $2.  How many hours does the stand need to run to make $200 in sales?
  Work out the solution step by step.
conversations.from: assistant
conversations.value: First, we find out how much in sales the stand makes each hour by multiplying the number of hot dogs sold by the sales price, finding that 2*10=20 dollars in sales each hour.
  Then we divide the sales goal for the day by the sales per hour, finding that the stand needs to be open for 200/20= 10 hours to hit its sales goal.
