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

### Instruction:
 Victory na Sam wamehifadhi pesa kwa ajili ya matumizi ya likizo yao. Victory anahifadhi $100 chini ya Sam. Ikiwa Sam anahifadhi $1000, kiasi gani ni jumla ya pesa zilizohifadhiwa kwa matumizi ya likizo?


### Response:
 Victory anahifadhi $1000 - $100 = $<<1000-100=900>>900 kwa matumizi ya likizo.
Hivyo, jumla ya pesa wanazohifadhi ni $900 + $1000 = $<<900+1000=1900>>1900.
