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

### Instruction:
 Ng'ombe wa John anapima paundi 400. Uzito wake uliongezeka mara 1.5 ya uzito wake wa awali. Anaweza kuuza ng'ombe huyo kwa $3 kwa paundi. Thamani yake inaongezeka kwa kiasi gani baada ya kuongeza uzito?


### Response:
 Ng'ombe huyo awali anapima paundi 1 * 400 = <<1*400=400>>400.
Inaongeza uzito wake hadi paundi 1.5 * 400 = <<1.5*400=600>>600.
Hivyo, umeongeza paundi 600 - 400 = <<600-400=200>>200.
Hivyo, thamani yake imeongezeka kwa 200 * $3 = $<<200*3=600>>600.
