conversations.value: Carl wants to buy a new coat that is quite expensive. He saved $25 each week for 6 weeks.  On the seventh week, he had to use a third of his saving to pay some bills. On the eighth week, his dad gave him some extra money for him to buy his dream coat. If the coat cost $170, how much money did his dad give him?

conversations.value: Carl saved in 6 weeks $25/week x 6 weeks = $150
  On the seventh week, he ended up having to pay in bills $150/3 = $50
  His savings were then $150 - $50 = $100
  His dad gave him $170 – $100 = $70
