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 weight bench can support 1000 pounds.  He wants to make sure to stay 20% under that weight for safety.  If he weighs 250 pounds how much weight can he put on the bar?

### Response:
 Anataka kubaki pauni 1000 * 0.2 = <<1000*0.2=200>>200 chini ya uzito wa juu.
Hivyo anataka kubaki chini ya pauni 1000 - 200 = <<1000-200=800>>800.
Hii inamaanisha anaweza kuweka pauni 800 - 250 = <<800-250=550>>550 kwenye kiti hicho.
