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

### Instruction:
 Carrie anataka kusafiri kwenda New York. Anaweza kupata punguzo la 20% kwenye ndege ya $850 na Delta Airlines. Anaweza pia kuokoa 30% kwenye ndege ya $1100 na United Airlines. Ataweza kuokoa kiasi gani kwa kuchagua ndege ya bei rahisi?


### 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.
