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

### Instruction:
An animal shelter is having a pet adoption event where owners can adopt an animal for just the cost of the vet fees. Vet fees for dogs are $15, and vet fees for cats are $13. Eight families adopt dogs and three adopt cats. The vet donates a third of the fees they were paid for the adoption checkups back to the shelter. How many dollars did the vet donate?

### Response:
 Daktari alipata ada ya dola 8 kwa mbwa * dola 15 kwa ada ya daktari wa mbwa = dola <<8*15=120>>120 kwa ada ya daktari wa mbwa.
Daktari alipata ada ya dola 3 kwa paka * dola 13 kwa ada ya daktari wa paka = dola <<3*13=39>>39 kwa ada ya daktari wa paka.
Jumla ya ada ya daktari wa wanyama ilikuwa dola 120 + dola 39 = dola <<120+39=159>>159.
Daktari alitoa dola 159 * (1/3) = dola <<159*(1/3)=53>>53 kurudi kwa kituo cha wanyama.
