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

### Instruction:
John's dog has a litter of 8 puppies.  He gives away half of them.  He keeps one of the remaining puppies.  He then takes the remaining puppies and sells them each for $600.  He had to give the owner of the stud $300.  How much money does he profit?

### Response:
 Alitoa nusu ya kizazi hivyo alibakiwa na 8/2 = <<8/2=4>>4
Kisha akabakiwa na mmoja hivyo alibakiwa na 4-1 = <<4-1=3>>3 mbwa
Aliuza kila mmoja wa mbwa 3 kwa $600 hivyo alipata 3*$600 = $<<3*600=1800>>1800
Kwa pesa alizopokea kutokana na kuuza mbwa, alilipa ada ya mbwa wa kiume hivyo alipata faida ya $1800-$300 = $<<1800-300=1500>>1500
