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

### Instruction:
Belle eats 4 dog biscuits and 2 rawhide bones every evening. If each rawhide bone is $1, and each dog biscuit is $0.25, then how much does it cost, in dollars, to feed Belle these treats for a week?

### Response:
 Kila siku Belle hula thamani ya senti 25 * 4 = $<<4*0.25=1>>1 ya biskuti za mbwa na thamani ya dola 1 * 2 = $<<2*1=2>>2 ya mifupa ya ngozi ya wanyama.
Kwa hivyo kwa wiki, Belle hula $1 * 7 = $<<1*7=7>>7 ya biskuti za mbwa na $2 * 7 = $<<2*7=14>>14 ya mifupa ya ngozi ya wanyama.
Jumla, Belle hula $7 + $14 = $<<7+14=21>>21 ya biskuti za mbwa na mifupa ya ngozi ya wanyama.
