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

### Instruction:
There were 50 people on the city bus. At the first stop, 15 people got off. At the next stop 8 people got off and 2 got on. At the third stop, 4 people got off and 3 people got on. How many people are on the bus after the third stop?

### Response:
 Basi lilianza na watu 50 - 15 ambao walishuka kwenye kituo cha kwanza = 35 watu kwenye basi.
Kwenye kituo cha pili, 35 watu kwenye basi - 8 ambao walishuka = <<35-8=27>>27 watu.
Kisha kulikuwa na watu 27 + 2 walioingia = <<27+2=29>>29 watu kwenye basi.
Kwenye kituo cha tatu, 29 watu kwenye basi - 4 ambao walishuka = <<29-4=25>>25 watu.
Kisha kulikuwa na watu 25 kwenye basi + 3 walioingia = <<25+3=28>>28 watu mwishoni.
