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

### Instruction:
There was only enough room for 21 people on a raft if no one wore life jackets. There were 7 fewer people who could fit on the raft if everyone wore life jackets. If 8 people on the raft needed life jackets, how many people could fit on the raft?

### Response:
 Ikiwa kila mtu angevaa jaketi la uokoaji, watu 21-7=<<21-7=14>>14 wangeweza kutoshea kwenye mtumbwi.
Kwa kila mtu mmoja aliyeondolewa kwenye mtumbwi, jaketi 14/7=<<14/7=2>>2 za uokoaji zingeweza kutoshea.
Kwa jaketi 8, watu 8/2=4 wachache wangeweza kutoshea.
Watu 21-4=<<21-4=17>>17 wangeweza kutoshea kwenye mtumbwi.
