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

### Instruction:
Jenny's property tax rate is 2%. Her house is currently worth $400,000. The city is about to build a new high-speed rail project nearby, which will increase her house's value by 25%. Jenny can only afford to spend $15,000/year on property tax. How many dollars worth of improvements can she make to her house before her property tax bill gets too high?

### Response:
 Kwanza tafuta thamani ya uboreshaji ambao Jenny anaweza kufanya kwa kutoa thamani ya nyumba yake kabla ya mradi wa reli na thamani baada ya mradi: $400,000 * 25% = $<<400000*25*.01=100000>>100,000.
Kisha gawanya kiasi ambacho Jenny anaweza kumudu kulipa kwa kodi ya mali na kiwango cha kodi ya mali ili kupata thamani ya nyumba yake: $15,000 / .02 = $<<15000/.02=750000>>750,000.
Sasa toa thamani ya nyumba kutoka kwenye thamani ya uboreshaji ili kupata kiasi cha thamani ambacho uboreshaji unatoa: $1,000,000 - $750,000 = $<<1000000-750000=250000>>250,000.
