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

### Instruction:
Carrie wants to take a trip to New York. She can get a 20% discount on an $850 flight with Delta Airlines. She can also save 30% off an $1100 flight with United Airlines. How much money would she save by choosing the cheapest flight?

### Response:
 Carrie anaweza kupata punguzo la $850 x 0.2 = $170 kwa ndege ya Delta.
Hii itafanya ndege ya Delta gharama $850 - $170 = $680.
Carrie anaweza kupata punguzo la $1100 x 0.3 = $330 kwa ndege ya United.
Hii itafanya ndege ya United gharama $1100 - $330 = $770.
Ndege ya Delta itakuwa bei rahisi kuliko ndege ya United kwa $770 - $680 = $90.
