conversations.value: Ted needs 5 bananas and they each cost $2. To purchase the bananas, Ted needs 5*2= 10 dollars
  Because Ted needs 10 oranges and they each cost $1.50, Ted needs 10*1.5= 15 dollars to pay for the oranges.
  All together Ted needs $10 for the bananas and $15 for the oranges, so combined Ted needs 10+15= 25 dollars to purchase all the produce.
