conversations.value: I need help with this problem:
  After working out for 3 hours, three friends go out for lunch. Adam spends two-thirds as much money on lunch as Rick. Rick and Jose eat lunch of the same price. If Jose ate lunch worth $45, what is the cost of lunch for all three?

conversations.value: Since Rick and Jose's lunch cost was the same, Adam spent 2/3*45 = $30 on his lunch.
  The three friends ate food worth 30+45+45 = $120
