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? Give me reasons, before answering the question

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. So the final answer is 70.
