conversations.value: I'm stuck on this math problem: Lizzy had $30. She loaned out $15 to her friend. How much will Lizzy have if her friend returned the money with an interest of 20%?
  Can you help?

conversations.value: Initially, Lizzy had $30; she loaned out $15 so she has $30-$15 = $15 left
  Her friend is returning the $15 with 20% interest for a total of $15+($15*(20/100)) = $18
  Lizzy will now have $15+$18 = $33
