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

### Instruction:
Mr. Ray has 100 customers waiting at his fish market. He has 10 tuna, each of which weighs 200 pounds. Each customer wants 25 pounds of tuna. Mr. Ray's store is first come, first served. How many customers will go home without any fish?

### 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
