conversations.value: Please show me the solution for: Natasha has 3 times as much money as Carla, and Carla has twice as much money as Cosima. If Natasha has $60, and the three decide to buy goods worth the total amount they have and sell the goods at 7/5 of the buying price, how much profit would they make?

conversations.value: If Natasha has $60, which is 3 times as much money as Carla, Carla has $60/3=$20
  Together, Carla and Natasha have $20+$60=$80
  Carla has twice as much money as Cosima, meaning Cosima has $20/2=$10
  Combined, the three have $10+$80=$90
  If they buy goods with the amount they have and sell at 7/5 of the buying price, the total amount of money they will get from selling the goods is 7/5*90=$126
  If they earn $126 from the sale of the goods they bought with the money they had, their profit is $126-$90=$36
