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

### Instruction:
 James replaces the coffee for the household.  There are 3 other people in the house and everyone drinks 2 cups of coffee a day.  It takes .5 ounces of coffee per cup of coffee.  If coffee costs $1.25 an ounce, how much does he spend on coffee a week?


### Response:
 Les 3 autres personnes boivent 2*3=<<2*3=6>>6 tasses par jour
Donc au total, ils boivent 6+2=<<6+2=8>>8 tasses par jour
Cela signifie qu'ils utilisent 8*.5=<<8*.5=4>>4 onces de café par jour
Donc ils utilisent 4*7=<<4*7=28>>28 onces de café par semaine
Cela signifie qu'il dépense 28*1.25=$<<28*1.25=35>>35
