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

### Instruction:
John weighs 220 pounds when he starts exercising.  He manages to lose 10% of his body weight.  He then gains back 2 pounds.  How much does he weigh at the end?

### Response:
 Anapoteza pauni 220 * 0.1 = <<220*.1=22>>22.
Hii inamaanisha anapima pauni 22 - 2 = <<22-2=20>>20 kidogo baada ya kupata uzito kidogo tena.
Kwa hivyo, anapima pauni 220 - 20 = <<220-20=200>>200.
