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

### 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:
 Kuna watu 3+1=4 katika nyumba
Hunywa vikombe 2*4=8 vya kahawa kwa siku
Hii inamaanisha wanatumia 8*.5=4 unsi ya kahawa kwa siku
Kwa hivyo wanatumia 4*7=28 unsi ya kahawa kwa wiki
Hivyo anatumia 28*1.25=$35 kwa kahawa kwa wiki
