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

### Instruction:
 John used to buy 4 coffees a day for $2 each. They raised the price by 50% so he cut the number of coffees he drinks in half. How much money does he save per day compared to what he used to spend?


### Response:
 John dépensait 4*2=<<4*2=8>>8 dollars par jour.
Maintenant, il dépense 2*2*1.5=<<2*2*1.5=6>>6 dollars par jour.
Il économise 8-6=<<8-6=2>>2 dollars par jour.
