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

### Instruction:
Arthur has 3 dogs. They eat an average of 15 pounds of food a week. One dog eats 13 pounds a week. The second eats double this. How much does the third dog eat a week?

### Response:
 Mbwa wa pili anakula pauni 26 kwa wiki kwa sababu 13 x 2 = <<13*2=26>>26
Jumla, wanakula pauni 45 kwa sababu 3 x 15 = <<3*15=45>>45
Mbwa wa tatu anakula pauni 6 kwa wiki kwa sababu 45 - 13 - 26 = <<45-13-26=6>>6
