Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 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?


### Response:
 Carl a économisé en 6 semaines 25 $/semaine x 6 semaines = 150 $.
La septième semaine, il a dû utiliser un tiers de ses économies pour payer des factures, soit 150 $/3 = 50 $.
Il lui restait donc 150 $ - 50 $ = 100 $ d'économies.
Son père lui a donné 170 $ - 100 $ = 70 $.
