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

### 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:
He lost 220*.1=<<220*.1=22>>22 pounds
So after gaining some weight back he was 22-2=<<22-2=20>>20 pounds lighter than before
So his weight is 220-20=<<220-20=200>>200 pounds
