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

### Instruction:
 Bwana Ray ana wateja 100 wakisubiri katika soko lake la samaki. Ana samaki 10 aina ya tuna, kila moja ikiwa na uzito wa pauni 200. Kila mteja anataka pauni 25 za tuna. Duka la Bwana Ray linahudumia kwa utaratibu wa kwanza kufika, kwanza kutumikiwa. Wateja wangapi watakwenda nyumbani bila samaki?


### Response:
 Ana samaki pauni 2,000 kwa sababu 10 x 200 = <<10*200=2000>>2,000
Ana samaki za kutosha kwa wateja 80 kwa sababu 2,000 / 25 = 80
Wateja 20 watakwenda nyumbani bila samaki kwa sababu 100 - 80 = <<100-80=20>>20
